As a holder of an ENCTS disabled persons bus pass, I have an interest in this subject.
I think saying that every concessionary pass holder is an "entitled freeloader" is not accurate, as is bordering on the offensive for those who are on low incomes, have no access to a car, and are thus dependent on public transport more than most.
However, those people who do hold a concessionary pass must recognise that the associated free travel comes at a cost, which is borne by taxpayers who are not entitled to such concessions.
Here in Birmingham, for example, if you have a concessionary pass and need to travel before 09:30 Monday - Friday, you can show your pass and pay a reduced fare of £1 as opposed to the full fare of £2.40.
If you need to travel frequently at these times, you can buy an add on to your pass for £33 per month, which is about half the cost of a full price bus pass.
If concessionary pass holders were entitled to travel for free at all times, it could mean that the single bus fare was £2.50 or £2.60, which would be unfair to those who have to pay full fares.
Personally I would be quite happy to pay £33 for my concessionary pass all the time, IF it could guarantee the financial viability of local bus services.
There are many people in rural areas who are entitled to a bus pass, but the lack of bus services means that the bus pass is about as much use as a chocolate teapot. What is the point of having a bus pass if there are no buses?
To those who may be resentful of the concessions that disabled and older people enjoy, I would say that I presume you would want to have the benefit of similar concessions when you reach old age, or if you become disabled.
It is therefore essential that the ENCTS system is put on a sound financial footing, so that it can be sustained on a long term basis.
