While you're not wrong in the strictest sense, I feel like this sentiment is being myopic to the point malice. The network gained from going to a university full of likeminded and talented people as well as living in a city teeming with opportunity is huge. Not to mention generic quality of life improvements of living in a city, doubly so if you happen not to be a cis-het white man.

Starting money is not strictly necessary nor sufficient for success but it sure can smooth over life's pitfalls, which makes risk taking a hell of a lot easier.
