I would not be surprised if capitalism ends in the united states in our lifetimes, either peacefully or through violence. Consider the rapid onset of robotization, creating a largely unemployed (and unemployable) populace, with the intersection of current republican party attitudes towards the nonwealthy, which I think can be mostly summarized as "fuck you I got mine".
You may find a book called "Does Capitalism Have a Future?" by Immanuel Wallerstein, et al interesting; I did.
But a favorable alternative may be quite likely: the institutional
transformation from capitalism to a noncapitalist system of political
economy—an institutional revolution—could come about through peaceful
political process. If the crisis of capitalism is severe enough—a majority
of the population structurally unemployed, robots and computers doing almost
all the income-generating work but owned by a small number of wealthy
capitalists, the economy in deep depression—at some point a political party
could win electoral power on an anticapitalist program. Some governing party
or coalition would have to replace capitalist production, distribution, and
finances with a system that redistributes wealth outside the system of labor
market and profit-taking.
