Why focus on income gap as a problem rather than the inability to afford or enjoy (for whatever reason) a reasonable standard of living? [ Answer: it rouses emotions and is thus rhetorically useful. ] Re inherited wealth: let's be clear - there is no country in the world where slavery was not practiced at one time or another in Asia, Europe America and Africa.

As to inherited wealth, in the main, Marx's recommendations in the Communist Manifesto have been largely implemented for most of us (40% tax in the UK above a fairly low threshold).
