How much can children of famous people leverage their parents success into colleges/jobs?

I saw some of the PNC Father-Son/Child tournament this weekend, which was won by Bernard Langer and his son who works in banking in NYC. I noticed from social posts that his son went to Wharton. (Big golf fan), I've also notice that Phil Mickelson's two daughters both go Ivy League (Columbia and Brown I believe). These guys are golfers and appear to be knowledge, meaning they probably understand the value of an Ivy. I know the Mickelson family also used the same guy/specialist that got all the celebrities kids falsely into colleges (they deny he did anything false for them).

My question is more, how much do you think it helps the children of famous people to get into Ivy colleges or get jobs at funds? I'm sure it helps if they donate, or if say Bernard Langer promises to play a couple rounds with investors it probably helps the career. I'm just thinking, there are a lot of celebrities, athletes, and Wall Street/Tech people among others who probably want their kids in these schools, so can that be leveraged? Is it easier for Bernard Langer's son to get into Wharton because his father won the Masters twice, or do they not really care? 

(Side note: just as an example, probably top of every industry can get their kids in where they want, for example I'm sure Tom Brady's kids can literally just pick their college and probably almost their career. Maybe they don't want Ivy League, but I'm sure Brady can just pick up a phone and get them almost any kind of job. In the same vein, does someone like Phillip Rivers or Joe Flacco have that same abilitiy?)
