I had five years at Oxford University in England -- and neither tuition nor maintenance cost me a penny (both under- and post-grad degrees). This is all about to change, as the UK goes down the pay your own way route. What a mistake!
However, I would have to say, that very broadly, the American students I met, at both stages, (and there were a lot) were much, much, more highly motivated and focused than we were.
Academics I know who have taught on both sides of the Atlantic confirm this. I am afraid that I think that this does have something to do with the financial commitments that US university education demands. (This is especially so in the humanities, where in the US they are a passport to graduate schools).
I applaud your gesture, however.
