I don't think wanting to maximise your earning potential is pure greed. You can't say it's more than enough than what your family need unless you're in that exact situation either, the more you earn the more you spend and he's not going to have anywhere near this earning potential again after he's in his mid thirties. I don't think it's greedy to get used to a certain lifestyle and want to live the rest of your life like that and to have enough money left for your kids to do the same.

Whilst some players are earning hundreds of thousands a week I don't think it's unreasonable for someone in that same industry to want to earn 50k instead of 25k a week or even 35k instead of 25k a week.
