Success and SSGs

Which College doesn't matter.
Success depends on what not where you study.
 
The whole point of the university is not future success, but to find and form a group of like minded people that will be your social support group after you leave. The advantage of the elite schools is that they select for a highly intelligent, high achieving, diverse student body which increases your chances of finding a partner, and forming that critical ERSSG.  It is possible to find an ERSSG if you are so inclined at many universities, ERSSGs are small even at the elite schools, it is just easier if everybody is a potential candidate and the ER is a given for any SSG formed.     
 
It is important to choose a school with the type of people you will want to hang with. Wonky, geeky, nerdy, waspy, athletic, or whatever fits your social needs. If you fit their profile the chances are reasonably good that you will get in. If yo' daddy's rich and yo' ma is good lookin', a wonky school and political success is in your future.  If you wasted your childhood in a basement lab or science fairs, there are many tech schools to choose from. 

If you have the personality dysfunction necessary for the "success" as measured in the referenced articles, it doesn't much matter where you go to get the business skills you need. A willingness to exploit your employees, burn the world, or buy government subsidies is all it takes for financial "success."

If one already has a partner and SSG as many do when they finish their K-12 education, which college, if any, is necessary to acquire the necessary skills for success as defined by the SSG will be unimportant.  What you learn not where is all that is necessary.
