The scandal of parents paying to cheat their children's way into elite US universities has put a harsh spotlight on the ultra-competitive college admissions process, in which the haves hold a massive advantage over the have-nots. Thirty-three wealthy parents -- financiers, lawyers, and two famous actresses among them -- were arrested Tuesday as part of an operation that charged from $15,000 to millions of dollars to help them get their children into renowned schools like Yale, Georgetown, Stanford and the University of Southern California. The figure is 4.3 percent at Stanford and 5.5 percent and Columbia, two other top universities.
