Capitalism ain’t goin nowhere on its own.

Well, sure it is. It's going to fascism on its own.

(And I'd say, once you get into the full fascist stage, it's no longer strictly speaking 'capitalist' anymore. I'd define capitalism as 'rule by capital', but once fascism gets sufficiently entrenched, that's no longer really the case. At that point, power is no longer determined mainly by how much money you have, it becomes determined by your closeness and standing with the regime's leaders. Having lots of money often facilitates that, but it's no longer the primary driving factor -- the primary driving factor becomes ideological purity/loyalty and political pandering to the regime. And even those with lots of money can still easily fall out of favor with the regime for any ideological misstep, any perceived threat to or disagreement with the leader, and even those with large amounts of money can still be purged from the regime at a moment's notice. If it's possible for the regime's leader to suddenly decide he doesn't like you, so then the regime takes your capital away and gives it to someone more regime-friendly, that's not capitalism anymore.)
