Indeed, and one thing worth adding to this is that the system does not recover to the same state as before after each crash. These events always result in further wealth concentration at the top as majority of the population is forced to let go off assets to make it through the crash, while those at the top are able to scoop them up on the cheap. Thus, the working class ends up in ever more precarious situation and less able to withstand the next inevitable crash. Eventually the whole scheme collapses under its own weight, often in a violent fashion.
