The world revolves around, the peak of the industrial era was their time and they manage to enjoy everything they have worked for. If you checked the last world war II in 1945, subtract it from 2022, that's a 77 years difference. That was the beginning of the journey of old people we have today as to why they control the most wealth in the US. Though there is now a change of civilization from the industrial era to technology, that's why the new richest people are all coming from tech companies, for example, Elon Musk, Mark Zuckerberg, and other young billionaires.

Industrialization revolutionized the financial system with stocks and bonds but now that bitcoin is here kicking ass, we will soon dominate the system, there are going to be younger crypto billionaires that will soon shake everywhere.
