I agree with Ophelia. If I were doing the essay, i would choose Richard Branson. You could argure both sides i.e. born or made. Most people assume that RB is a self made millionaire, started from the bottom, traded from a barrow in the East End etc. He may have started from the bottom, but with the benefit of a wealthy background and the best education that money can buy. He would be ideal if the essay required the usual oxbridge style of writing i.e. selecting three arguments for the thesis in descending order of importance, and also three arguments against the thesis, again in descending order. You also get to slot in RB's quip that the best way to become a millionnaire, is to start as a billionnaire and buy an airline.
