the reverse of making state pension untaxed. A tory wheeze intended to appeal to their voter base.
I find the idea of a state pension that is universal, and taxable, extremely simple
Also, if rich people didn't get a state pension, they would lose interest in keeping it up with inflation.
In the same way that rich people using private schools and private hospitals have little interest in the quality of state provision used by the common people.
By chance, these rich people include those in government and those with good lobbying access to politicians and lobbying forces.
Can you see a pattern?
