Has capitalisim reached it's endgame ?

I’m not highly educated when it comes to world economics, however I was pretty good at the game of monopoly and when the gameboard and finances were so heavily in one players favour, then it was inevitible that the game would end soon.
I now have some understanding that the US and many other economies are so in debt that it is almost impossible to recover (with the present system).
Other things like prision privatisation, where the prison owners get so rich that they gain the political strength to change laws in order to get richer, Then elite players such as the Rothschilds who have been in the fortune/power game for centuries.
Am I wrong, isn’t this system like a game of monopoly? If so, there will be only one winner in the end, it cant last forever.
