>Hardly. The Friedman doctrine didn't exist prior to 1970; does that make every business venture prior to that a statist-collectivist enterprise? Are privately-owned companies the expressed goal of Marxism? Of course not.
>The whole "if you don't have a bunch of free riders participating in an equities market, it's Marxism" bit is an intentionally obtuse argument.
To be fair, Marxism can roughly be summarized as "workers should own the means of production, capitalists are exploiting workers by leeching off what they produce", and what you've said so far about shareholders being "free riders" and that "corporate profits returning to shareholders at the expense of workers and customers" isn't too far off from that. The fact that you refuse to directly answer my question of whether shareholders should get any money doesn't help your case either. In light of all of this, I feel like asking whether you're arguing for Marxism was totally justified.
>Current schools of thought essentially dictate that management and investors treat that share as if it can be unlimited. Anything that could possibly limit returns (taxes, regulations, labor movements, consumer rights, etc.) is an externality or to be eliminated. Otherwise, it gets in the way of profit, and since most economist types have a limited ability to understand anything beyond the absolute simplest of abstractions, profit has to be the ultimate measure of social good. Therefore, those things stand in the way of social good.
Capital and labor are both trying to get as much share as possible. I don't see how either side is any different. If anything, labor has actually been more successful, because their share is currently above 50%, and actually got their share to 100% in a few places (ie. communism). Meanwhile I'm not aware of any instances where capital's share is 100%, except maybe some edge cases where capital and labor is the same person (ie. self employment).
>We should make it higher.
Why? More to the point, what do you think is an equitable split?
