It isn't how much money but how you make it.
No billionaire ever made their money without necessitating the exploitation that is inherent to being an owning class citizen. Yet, there are also plenty of people of much lesser net worth who exploit workers all the same, just to a smaller extent.
Remember the problem isn't just billionaires but the system that enables their existence and those who willingly choose to perpetuate it.
This is a very naive way of thinking that comes from a propagandized view of revolutions and ignorance of history on all the efforts that came before which allowed those revolutions to happen at all. It doesn't come together quickly. It is explicitly the result of having a community foundation and culture to build revolutionary effort on which took years of concerted effort to reach that point. Organizing doesn't happen spontaneously nor quickly. Anyone who told you otherwise was lying to you.
The ruling class has systematically been dismantling that very foundation since the Taft Hartley act.
The same risk of starvation that pushes people to revolution also pushes them to obedience to strongmen who promise to fix their problems by removing the "undesirables" who are being blamed for the misfortune. Without the proper working class culture of solidarity and a community foundation, people are more than likely just going to turn on their neighbors than they are to work with them, especially with the culture of hyper-individualism and xenophobia that the US has cultivated.
If we fail to build back that foundation, people are just going to sell each other out for their next slice of bread.
