Man, I feel like I wrote a paper on this in college or something lol.
Basically, capitalism invented the joint-stock company, and then the modern corporation and managed investment funds.
Marx's problem ultimately is labour alienation. I.e. that the "capitalist" exploits someone's labour and doesn't adequately compensate him for that labour, etc. His solution is revolution and labour soviets governing manufacturing firms, and so that's what we saw in communism. For him, since the worker now votes for what the company does, his labour is now his "own", from like a broke ass obi-wan kenobi sorta point of view, and alienation is "solved" according to him. And that's cool for a 19th c. pov I guess...
Modern western, or at least american, capitalism has a high degree of participation in stocks. Some dumbass 19 year old commie wants to bitch about "the shareholders" as if they're evil shadow men or something, but the reality is, you are the shareholder in most cases. I mean even if you're not a consumer trader stonks bro or someone with a bespoke stock option in your own firm, you probably still have something like a 401k or some kind of managed investment fund where you have shareholder ownership in multiple companies managed by your investment manager. You are a capitalist. Even if you're a little dude at 25 or so, if you've been running your little 401k since you were 20, you probably have 20k-30k set away, and while it's not immediately available to you, you can usually lend to yourself from it, or even withdraw from it to do things like first home purchases or to avert disasters like eviction, etc.
And it totally fixes labour alienation. You, again, are the capitalist. That fund exists based on the managed stocks you own which are shares of ownership in "the corporations".
If things are fucked up for you, it's because you likely are either just not earning money to begin with (which would suck in the USSR too), or you're just not familiar with the financial instruments available to you. In the US though, there are infinite little means where you can become a partial owner of "the corporations", and use that to your advantage, and secure anything from real estate to your own retirement.
Because of all that, the people who are capable of organizing a revolt simply aren't interested because they don't have a need to, and the people who are bad off, are bad off because they're too stupid to make use of the instruments around them, and are much less able to organize a revolt.
