Inequality 1/2:
In the Observer today, Eliza Filby (in an article summarising her new book, not yet online) uses a term I'd not heard before & like (but which doesn't originate with her):
the Inheritocracy
As she points out int he article & in her book, Britain has become a society patterned by what you inherit from your parents, alongside what after net they can provide as you build your life.
In other words (as I've posted on before) inheritance is an engine of inequality.
