Earlier quoted context omitted.
Rigged isn't a fair word, it's just reality. It's only reality because people accept it. If we stop accepting it the reality can be changed. For example, for several hundred years many people accepted slavery and believed owning people was justifiable. When enough people decided not to accept that reality it was changed fairly quickly.
Sorry to be a bit pedantic, but reality exists independent of belief or acceptance. However, a belief in whether or not a person can change that reality at some future point, I think is a more accurate description of the quality you're describing.
It can be similarly argued that the modern income/opportunity distribution owes its continues existence to the fact that enough people believe that it exists and is lawful.
