What, then, should be done? In the short term, the most feasible approach is to impose a capital gains tax charge at the current rate of 28% on the topmost layers of wealth, the £155bn gains amassed by the 0.003% over the last three years.
This is a tax on unrealised gains you understand.
So, they must liquidate some portion of their holdings in order to raise the cash to pay the tax.
So, err, who do they sell it to? All other rich people face the same problem and not rich people, by definition, don\’t have the cash.
