Dubya got into Yale courtesy of daddy. The kid wasn't bright enough to get in on his own. Perhaps Harvard also accepts legacy kids. Who knows? But the rest of the kids have to sweat their asses off to get in.
"Liberals feel that anyone who wants to immigrate to the US should be allowed to get in."
Please provide proof of this.
Barack Obama made it to Harvard, and he was not a privileged kid. Both Bill Clinton and Rachel Maddow made it to Oxford, winning Rhodes Scholarships. They were not legacy kids. We don't need to dumb down education. We need to get kids away from their video games and cell phones, away from tinkering with cars, away from ogling ill-clad "cheerleaders" or becoming ill-clad "cheerleaders" themselves, away from trying to find who sells beer, and get them to crack the books and compete.
Years ago, there was a guy at my company who was Vietnamese, fled Saigon. His English was not so great. He sat his kids down every night at the supper table and supervised them doing their homework. Result: three engineering graduates from U. Va. America seems to be full of quack parents who either don't know how to do this or are too negligent to do it. It's up to the parents.
