I don't think we should be interested in the "asymptotic theoretical limit" of capitalism which is never reached. Let's discuss "capitalism in practice", not "capitalism in theory". If things self-correct in a time frame longer than your own lifespan, do you think it's an ideal scenario? I personally don't.
I don't see the government forcing Google to pay thousands of highly qualified workers to fill in BS jobs. This is a natural consequence of being a very successful business: complacency, empire building, etc all decorellated from economic incentives.
People spend decades with BS jobs in a very capitalist society.
Note that I've never argued that a socialist alternative is any better or that the government isn't filled with BS jobs either.
I just observe that the problem manifests itself regardless.
If there is not a better option, then yes.
And yet if you spend any time in any large corporation, you'll find countless examples of these, including in the tech industry. Don't you have any friend working for Google/Meta/${big tech co}?
Bullshit jobs can and definitely exist with capitalism: any successful and large business is filled with them.
