That's the best way to do it. Otherwise all the money will go to the rich brat children of politicians/etc who are socially connected to whoever they put on the selection committees.
I agree that it's a problem. But how do you prevent it from been overflowed by people like me that can't draw a circle with the bottom of a bottle?
I'm not sure that's true. What kind of rich brat will go through the trouble of all that for a couple hundred euros a month?
Random isn't a bad way of doing it in any case though.
