How did Michelle Obama go to Princeton University?

Yes, Michelle Obama attended Princeton on a scholarship and also her brother attended Princeton on a scholarship, because their parents couldn't afford to pay for college.

She attended Princeton on a scholarship because of her Excellent academic record, not because her parents couldn't afford to pay for college. Mr. and Mrs. Robinson could not afford to send their children to Princeton, but no worries, because Michelle and her brother were both extremely smart. If Michelle and her brother attended Princeton on a scholarship because their parents couldn't afford to pay, then everybody whose parents can't afford to pay would get to go to Ivy League schools. No, she got a scholarship to Princeton, because she was academically talented enough to get one, unlike most of us. For the rest of us, when your parents can't afford to send you to college, you get financial aid, and not a scholarship to Princeton!
