I am going to use a comment from another person from somewhere. "its totally fine buying a degree and getting in prestigious universities. What is not fine is that you didn't pay enough" "Back door" has always been available for the rich people and front door for the people that want to do it the old fashion way. Money from the "back door" in theory helps the "front door" people, but "side door" is bad because the money doesn't go towards giving "front door" more resources AND they didn't pay enough to justify getting in.
