This is absolutely an opinion you're entitled to hold, but the vast majority of folks who quite happily live outside the "triangle bounded by Hove, London and Dover" and live happy, fulfilling lives and earn a reasonable wage are going to roll their eyes at these assertions.
Some of the figures mentioned in the OP have already been picked apart by other forum members, but I think the perspective expressed in the first post suggests a very short-sighted view on what it's really like to live outside of the south east.
Places like Warwickshire are actually pretty decent, for example, and my house even cost less than 400k! Do I like visiting London? Sure, and I can acknowledge it does have a lot to offer in terms of night-life, things to do, shopping etc.
Also, as a software engineer, I'm surprised you're concerned about the physical location of potential job opportunities when there are so many remote or mostly-remote opportunities.
The reason I landed at Bournemouth last year was that I was training for a life challenge and my friend advised me either Dover or Bournemouth. Bournemouth is the less evil among the two places since there is absolutely nothing in Dover. Unfortunately, due to a number of reasons, including pandemic closures before moving to the UK and the lack of facilities in Bournemouth afterwards, I failed the challenge in last September as my training was far from what I should have done. And after the failure I pissed off everyone I knew in Bournemouth.
I planned to move away afterwards but, as a coincidence, I found a job in my desired industry and the company happened to be in Bournemouth. That job paid much less than the market rate in London, but more than the elsewhere market rate, and a car would be affordable for me with that salary (that salary could afford luxury outside London, but would just offer a basic level of lifestyle in London). I looked into options but didn't get one after I made my calculations, and joined a car club instead.
However, despite I was earning salary, my qualify of life was so low as there is nothing in Bournemouth for me to enjoy apart from the beach, and my body isn't strong enough to swim for hours multiple times a week in the sea during the winter. A major part of my leisure is doing orienteering races, which, by its very nature, requires travelling to different places. This is why I insist in choosing a place with good transport connection. I bought train tickets week over week, and they are certainly cheaper than the fuel cost alone of driving a car. Note that it isn't possible for me to use an electric vehicle because of the inability to charge the car in a rural area while I'm out racing, and the range of a typical EV isn't enough for me to have a complete day out into e.g. Sussex, Berkshire, etc. from Bournemouth (also as my home doesn't have parking with charger I will need to put it at a public charger, and pick it up again after a few hours which is a major inconvenience, especially after a long day out in the countryside returning home late night).
The area in Bournemouth with the best public transport is the section between the town centre and rail station, including Lansdowne - nearly all buses from the town centre pass through Lansdowne to the rail station, then continue somewhere else, and the existence of university campus / accommodation guarantees ridership. So local travel was never a problem for me using bus and cycle hire, but unfortunately regional travel is a real problem, given the dominance of the railway in the UK for long-distance travel and the late starting time on Sundays.
Unlike popular opinion on this forum, I regard train travel in the UK is cheap as I travel on off-peak and advance purchase fares using a Railcard, and a lot of my regional travel goes via Barnham which is a real bargain. Train fares for me are definitely cheaper than fuel cost if I drove instead.
However, the regional public transport connection from Bournemouth, or in the west of the country in general, is so bad that effectively I couldn't get to most races in the South West, and I had to travel further on the Coastway (using cheap via Barnham tickets) to do races in the South East. For example, if I use public transport on a Sunday from Bournemouth, the first available itinerary will get me to Castle Cary after midday. There is a direct express bus route from Bournemouth to Salisbury but it doesn't make a useful connection to any onward train connections to Bristol, and the very few coaches don't run at a useful time, and I have to waste time by going through Southampton instead. For the most important races, such as the British Championship, if I really want to do it I am forced to hire a car which is costly even that the location is normally reachable by public transport (but it is still less costly compared to car ownership).
Furthermore, if I want to have a longer trip, it's simply impossible (or very costly) while having a full time job if I live in Bournemouth, because Bournemouth Airport is a dead airport with nearly no air services in the winter, and it serves mostly holiday beach destinations (who actually wants to fly to a beach resort when Bournemouth is itself a beach resort?!) instead of domestic city destinations (such as Edinburgh), and Southampton Airport can't host low-cost airlines due to its short runway, which Loganair can easily charge £300 for a flight to Edinburgh as there is no competition, 4 times the cost from Gatwick. And the lack of high-speed rail connection to Manchester means it isn't possible to complete a journey on land to Scotland in the same evening after I get off work on Friday, which, depending on destination, if it is further than Edinburgh the only way to get there on time for a Saturday race is to fly expensive Loganair from Southampton, stay a night at Edinburgh, and continue travel on Saturday morning, or go to London in the evening and use the expensive Caledonian Sleeper from Euston. My trip to Dundee for races wouldn't be possible if I didn't lose my job, as I had to travel from daytime on Friday to get there in time unless I use the sleeper, and using air would be cumbersome and involve multiple undesirable connections with little time / fare advantage compared to the freedom of a super off-peak train ticket straight from London. Note that this is irrelevant if I have a car or not, as the journey is too long to be made using a car.
Although my job was in my desired industry, I actually felt relieved when I lost it as it would mean the end of my crap Bournemouth life. I believe it will be possible for me to do everything I want while having a full time job in London, which isn't possible in Bournemouth. After I move to London I will first complete a train timetable website first, then depending on my situation find another job or start a business.
I get £300 insurance (cheaper really, because it includes breakdown cover) because I have a clean driving record. No history of claims, accidents or motoring offences. Unfortunately if you don't have a no-claims history you will pay a lot more because you represent a higher risk to the insurer.
I also don't have a history of claims, accidents or offences, because I have no history at all.
My commute by car is 15 minutes. It used to be a bit longer but there's less traffic since Covid. On the bus it is supposed to take 40 minutes because it goes round the houses. Even with less traffic it's usually late.
That's pretty bad. If the car commute is 15 minutes and the bus commute is under 30 minutes (including waiting time) the bus will have a great value.
I will add, though, that before I moved here, I spent 12 years commuting into London. I enjoyed the time I spent in London, but I don't miss those journeys.
I don't know about Hong Kong, but London meets that definition. I know working from home has changed the world, but look how many bankers used to get off the tube at, erm, Bank, and Canary Wharf.
Thanks for pointing out that.
But if you can't afford to live there, then it won't provide the lifestyle you want. You won't be able to enjoy the city if you have no money.
Jobs in London commonly pays £50k - £60k or even more for my occupation, while elsewhere in the country £35k - £45k is the norm.
What do you think is a reasonable commute? When I worked in London, my commute was normally about 30 minutes but that's because I lived in St Albans and worked near Farringdon. I think I had one of the shortest commutes in my office. I was often got home before people who actually lived in London.
You are lucky to have your office at Farringdon (the centre of the railway), which makes a commute by rail from Luton / St Albans actually feasible. However, by living at St Albans, you are limiting your commute to the Thameslink line, which ruled out potential job opportunities in e.g. Canary Wharf (at least before the Elizabeth line opens).
