That's complete nonsense. It is quite clearly disproved by the collection of Old Etonians currently in government. All of them gave up making more money in the private sector - from their own efforts rather than Daddy's money or nepotism - in order to enter politics. One can't say that of the contemporary Labour party. 2 of Corbyn's 3 sons were employed by their father, one also working for McDonnell, political advisor daughter of a leading trade unionist; many Labour MPs are beneficiaries of a family history or nepotism in the Labour Party - Hilary Benn, a FOURTH generation MP; Milibands, Kinnocks, Vaz, Thornberry, Falconer, Elliott, Cunningham, Straw, Hoyle, Prescott etc etc. The BBC is no better either.
