The problem is that the only charismatic conviction politicians are extremists.
So you get the ultra woke left wing where all immigration is good and the more ‘protected characteristics’ you have, the more society owes you vs the xenophobic right wing where no immigration is good and platitutidinous easy (but unworkable) solutions are put forward (Trump and Farage).
In between you have people like Starmer and Sunak who are technocrats with little conviction about anything but basically decent people who want to make society work better but have little idea how to do it except on the margins, so they flip flop from ‘big idea’ to ‘big idea’ (which are really small tweaks anyway).
And we have a society with entrenched interests who can easily block the technocrats, so we have an inability to build houses, control our borders, produce power at a sensible price and have a working transport system.
It is a a global problem but we have it particularly egregiously.
Musk’s putative £80 million is a pittance in the scheme of things and can only influence politics if it is pushing on an open door, which I think it is.
