Capitalism has been struggling with the problem of collapse, and in fact it did from pretty early on in that history you mention, with Italy, Germany, Japan, Spain, and so on. The problem isn't just going to go away, because a system that needs infinite expansion in a finite world necessarily will collapse. It can sometimes "innovate" its way into having more time, and modern imperialism is just such an example of that innovation, pushing much of the poverty capitalism demands into the third world, but that just changes the specific circumstances of the problem rather than eliminating it. The US as we speak is continuously losing its grip on its hegemony as the imperial periphery and semi-periphery develop sovereignty. History will not end.
