We already have marginal tax rates of over 100% for people with childcare expenses who earn £100k, so hardly anybody bothers to earn more. The reality is that our (not wealthy) relatively high earners pay some of the highest taxes in the entire world.
It is the lower and middle earners in the UK who pay far less than those in comparable countries with functioning services because mathematically there is no other way to fund them. The UK electorate needs to get real. The only realistic choice is between the average and lower earners paying far more or there being far lower service provision.
If cakeists keep promising the impossible and a gullible electorate continue to believe them then eventually the bond market will force the tax rises and service cuts because the country cannot sustain itself as it stands. That will be far more painful than making slow and gradual changes now.
I don’t agree with cutting disability benefits BUT huge changes need to be made to make unemployment benefits time-limited, change the NHS to a French/ German/ Australian system, make huge changes to the state and public sector ponzi pensions and to social care funding so that people pay far more of their costs themselves (not just responsible people who’ve chosen to save, but everyone being forced to contribute properly to these things and pay their fair share).
