Forcing taxpayers to subsidize wealth of billionaires and corporations has nothing to do with capitalism. In capitalism, you let free market do the work, and if major corporation or a big bank fails, then so be it, its owners should have done better.
If anything, the current system is resembling a disgusting fusion of bolshevism and oligarchy, where corporate elites merge into one monstrosity that taxpayer is forced to foot the bill for, bypassing both free market and even basic democratic institutions.
So no, capitalism isn't the problem, American elites are a problem as well as archaic and obsolete federal reserve and fiat monetary system.
