The very top sliver who own the majority of the land and assets and who never need to work a day in their life are who must be looked at; that hereditary wealth needs to begin to find itself flowing into public services more and more.
Perhaps you should check the facts before making statements like that!
So it says there are 57 billionaires in UK with total worth of £182 billion. Non-billionaire wealth is £10.13 trillion, btw, so it's definitively not 50%. UK population is 68.3 million people. So everyone gets their £11,311 and that's it.
UPDATE there are £772.8 billions if you include non-UK citizens, but happen to live here. If you seize their money as well that will give you the total of £11K
