You are also forgetting that for most people a large proportion of their money is taken up with food, accomodation, bills, petrol etc. etc. Whilst I have no doubt Marcus spend more money on nice food, houses, cars etc. etc. It will still be a much lower proportion of his income.
Basically what I'm saying is that ML can put a much higher portion of his income towards 'recreational', for want of a better word, prospects.
