One simple metric of inequality in the UK:
in 1980 the ration of median FTSE100 CEO pay to median UK wages was: £1 - £11;
In 2022 it had become £1 - £118.
I think it's safe to say that is not commensurate with the improvement in the conduct & success of the top management of UK corporations; nor, should it be said, a fall in the contribution to the UK economy of the work of the general population.
The rentiers (as we know) have stolen our wages.
