I know - really stupid isn't it?! Neither of my parents did for me that's for sure - and one of them is a Professor of Education! One of my friends got money from her parents (one of them was a banker) and then went to Cambridge - guess the friend wouldn't have been able to do it without a little incentive (the same family also paid for tutors and even paid of Prof. of English to read coursework, and probably the PS later although I don't know about that for sure!).
Think there's nothing wrong with seeking a little help when you need it but there's a limit to what's ethical. Anyway, in the long run it's much better to be able to help yourself than to rely on external motivation (that might not always be there!).
