Your post doesn't tally with reality.People have got fed up or society decaying as it’s been completely malnourished from any serious investment in public infrastructure for a long time now.
It’s been 13 years since the Tory’s told us to tighten our belts for the greater good of our future and in that time the country hasn’t made the grand recovery that was promised then. In recent years the state of the economy has only got worse.
If 13 years isn’t long enough how long must we wait? 25 years? 50?
Neoliberalism is a good idea. But it doesn’t work in practice!
The tax burden in this country is higher than at any time since WWII. The current government spunked more money on lockdowns than on any other project that I can find the cost of anywhere.
The problem isn't a lack of taxation or spending, the problem is that we're being constricted by too much of both.
