Exactly. Just as important as Ivy education was their baseness and corruption.
Any honest and decent person wouldn't have made it to the positions of the above mentioned illustrous characters.
A lot of business graduates from small, less well known colleges went on to open small businesses.
Which isn't a bad thing... and "small" businesses generally pay-off attending "lesser known" colleges.
Decent people learn that lesson by mid-career and leave to start their own companies. Probably why the government hates small business owners so much - they aren't easily corruptible.
An Ivy League education is indispensible if you intend to rise to the top of a Fortune 500 company or a major political party. But so are sociopathic tendencies. ;)
