Collection of taxes from offshore companies and closure of tax loopholes. Reframing of priorities. Cancellation of Road projects and HS2. Investment in government-funded projects aligned to environmental change: bike lanes, green power plans reclaiming the countryside, labour-intensive farming. Building green council housing. Invest in teachers, defund special advisers.
OK, to pick out a couple of your ideas.
Collecting taxes from offshore companies & loopholes is one I could get behind, but there has been a huge amount of pressure on successive governments to cut out offshoring so I'm not sure this current government would have the will, or the ideas to do this. And even if they did it might need years of legislation to get to the point at which we could start to recover the losses. Unfortunately we need solutions that can be in play a lot sooner.
As for large scale projects like HS2 we've been down this road before on the HS2 thread. The cost of that project is spread over the entire lifespan of it. Cancelling it would offer only a tiny fraction of the funds made available immediately, if at all. And it kind of contradicts your next ideas for government funded projects, of which this is definitely one. Finally farming would be another nice one to have, but a lot of our countryside is privately owned and not available for farming. So its another measure that would take many years to get into play.
And so we get back to the original problem. The cost of covid, both directly & indirectly is going to be felt in this financial year. We need solutions for that now not years into the future if a lockdown is to be continued.
