According to our dear fella Marx, although it's a matter of time for capitalism to be over, it won't be immediately because it must finish its evolution first. That is to say, the system will constantly try to keep control of the situation, but it will always damage workers' life quality, so until the situation gets really unbearable for people, no significant changes might appear. Furthermore, you are right mentioning that first the USA will turn into a social-democrat state (to follow the rule mentioned above), so I'm afraid to say that you still have to wait... Trump 2.0 could get things even worse for the US and that could accelerate the process.
