SL, in the U.S. it is not necessary to obtain an education to be "successful", at least in financial terms. (Do note that people have different philosophical views on what "success" means, but let's stay on finances for now.)
Famous billionaires who dropped out of college include notables such as Bill Gates (Harvard), Larry Ellison (Univ. of Chicago), Paul Allen (Univ. of Washington), Michael Dell (Univ. of Texas), Carl Icahn (NYU), Kirk Kerkorian (high school dropout), Steve Jobs (Reed College), Ralph Lauren (City College of NY), Richard Branson (high school dropout). Though it is possible to argue that in the past circumstances were different, which allowed entrepreneurs to hone in on emerging technologies and new ideas.
Now with the "globalization of markets", students are competing not only with fellow graduates of a class but with others throughout the world. It's a sad state of affairs in the U.S. when we can't educate our own people. In a disasterous turn of events, I can imagine the U.S. becoming the next China - offering cheap unskilled labor for other countries, as the educated elite flee.
