This has to do with the lack of economic mobility. When 100 million poor families try to their get kids to 500,000 spots in top schools, this is an expected result. The 'how' of getting to these spots varies: test prep (in China and India); well-rounded ness, volunteering in Africa, exotic sports, (for kids in the US); etc. When one path is made harder, the problem (of poor people trying to move up the economic ladder) does not disappear.
