You're point about the self-correcting feature of capitalism is well-taken - which is one of the reasons I am a capitalist rather than a socialist.
However dramatic business cycles are part of capitalism and George Soros - among others - argues against its inherent stability. And there are plenty of modern examples of great falls with huge consequences. So one can say the self-correcting feature is far from perfect.
Also, while it is true that socialistic endeavors can have plenty of adverse consequences, they can also work very well - and have in areas that for one reason or another are not suited to the capitalist approach.
I realize that we are both speaking in short-hard due to limitations of space and time. I hope I've been successful in making myself clear.

Socialism can work in a less complex society.
