The next government's best hope of being 'better' is to prove that they are better managers than the Tories have been. That's not a high bar. You could do a lot just by cracking down on tax fiddling and pure corruption.
I don't expect the next government to be one long multiple orgasm because we have to be realistic. A lot of the issues people go on about are not easily solved. The Wizard Merlin will not be in the Cabinet. However, I believe Starmer and his people - while very far from what I would ideally like - are not corrupt shysters who will promise the world and deliver SFA. So that is something.
My issue - which would apply to any government - is that I am very doubtful there are efficient delivery systems in place to deliver anything. That is due to many years of Tory fanaticism and obsession with private-sectoring everything.
