By that description, we can draw a line around the people born in regular old middle class households, and another line around the wealthy, and imagine them trading with one another, much like poor countries in the mid to late 20th century, that are now wealthy. This should demonstrate there is nothing holding back the rest of this country's population from getting wealthy too, while some rich kids inherit from their parents, or go to some rich-kids-only-(except-not-exactly) university.

A different situation is if some wealthy people engineer things so as to effect transfer payments from the middle/poor classes (or just everybody in general) to themselves. I.e., rent-seeking, which obviously exists. While I don't like legacy admissions, afaict it's not rent-seeking.
