$40k is an average full time age after tax and student loans in the U.K
But we’d rather tax workers to the hilt to pay for wealthy old people. Isla refreshing to see the op mention that “savings” are just a claim on future work. When there’s 10 billionaires who need care and 2 people who can provide it, how much will those carers charge.
The other solution is high immigration. If you can import 18 year olds it’s win win win. At least for old rich people. Keep wages down, no tax money on new generations.
