I see a lot of comments saying workers are not allowed to own what they produce. That their employer takes it from them. I feel this is flawed and possibly comes from a place of frustration.
That's not frustration. The viewpoint you are describing (that workers are not allowed to own what they produce) actually comes from a different definition of "capital" and "capitalism" than the one you are using. And that difference in definitions is why I created this post. And I appreciate your answer. It lets me highlight the differences in definitions and the consequences of those differences. Because in the case of capitalism, the difference in definitions are actually more important than any difference in values or priorities.
You noted that people are saying "workers aren't allowed to own what they produce in capitalism." But those people are not referring to capitalism as you have defined it.
Capital
Capital is a combination of property and money. Property being the things you own, with money being a measure of potential property you don’t yet own.
I'm sorry, but no one who disagrees with you thinks that the ability to accrue property and money deprive workers of control over what they produce. Not even Marx and Engels. Not even Mao or Stalin. Certainly, property and money can we wielded in such a way that they become capital. But until then, property and money are merely wealth.
The definition used by people like Marx and Engels -- or by the entire field of economics -- is: capital is property that allows or speeds up the production of goods. A mine. An oil rig. A McDonalds burger conveyor-belt-oven-thingy. A 3D printer. In other words, the word "capital" is about the function of the property. Not its value. A painting can cost $1,000,000 and still not become capital. Because no one will ever operate that painting to cook burgers. Or to mine ores.
Capitalism
Now "the ability to own commodity-producing property" is still not quite sufficient for a system to become "capitalism." In fact, Marx and Engels didn't want any capital to be destroyed at all in the overthrow of the bourgeoisie. Because even under the definition of "capital" that communists still to this day believe in, the existence of capital and ownership of it are still not inherently a source of coercion.
There's another crucial piece to the puzzle that leads to people complaining about the whole system:
In capitalism as a system, some form of employment contract always allows the owner of capital to own everything produced using that capital.
For example, the oil rig owner -- according to employment contracts -- owns all of the oil produced using the oil rig. But not only did the owner not need to work the rig to extract the oil: the owner also did not need to weld the seams or turn the screws to build the oil rig. All the owner needs is official ownership of the oil rig and a system that acknowledges their right to everything the oil rig produces, (regardless of who needed to input their labor to turn the oil rig into anything other than a metal sculpture in the ocean.) and with those two things, they are entitled to all of the proceeds of the rig.
Now, hopefully, you can see that, provided a worker has entered into such a contract, "workers are not allowed to own what they produce" is not a statement born from frustration: it's just true by definition. It's not saying "the worker is NEVER allowed to own anything they ever create in this society." It's saying: "within the relationship laid out by the employment contract, the worker who operates capital is not entitled to the direct consequences of their labor."
Now, whether the worker benefits from this arrangement is another picture, but in accepting an employment contract, the worker is entering into a dynamic where they do not own the outcome of their own labor.
Bonus Question #4
Which is why bonus question #4 (the difference between a workers' cooperative and a company that uses these employment contracts) is extremely important to understanding the consequences of the difference between these definitions. You even touched on its importance in your earlier replies, saying yourself:
If that worker is employed by a sprocket making company; they still make sprockets, but that’s not what they produce. They produce labor. Which they’ve chosen to sell to the sprocket company for money and/or other benefits
(Aside: what you're describing here is literally Marx's theory of alienation.) But more importantly,
I'm assuming the sprocket company "produces" sprockets by your definition of "produce." Well, in a workers' co-op, the workers vote in the decisions of the company. They elect the CEO (if there is one) and the managers. They take shares of the profits. They are the company. And if the workers are the company, and the company produces sprockets, then the workers are once again -- just like if they were self-employed, but with the benefits of efficiency and networking that come from being part of an organization -- producing sprockets. They are no longer (as Marx would say) alienated from the results of their labor.
In other words, the co-op is a form of self-employment according to the definitions you appear to be using. Which makes the distinction between cooperatives and other kinds of companies... massive.
The people saying, "capitalism strips workers of the results of their labor" love workers' co-ops. Love them. Despite you probably defining the workers' cooperative as "another example of capitalism", not even avowed Marxists would in any circumstance suggest that the worker co-op "disallows workers from owning what they produce." In fact, they strongly believe the opposite. To them (and to Marx himself) the worker cooperative operates under an entire opposing paradigm to the worker contract. And to them, it is therefore a rival philosophy to capitalism.
You don't have to accept their definitions. You don't need to believe Marxist definitions are correct. You can believe co-ops are capitalist all you want.
But please: try to understand that when people criticize "capitalism," they are (I 100% guarantee) referring to something far more narrow and far more specific than what you call capitalism.
I'm with J Lou. Even Marx considered capital a valid input to the production process. He just thought it was being misused.
He believed the workers should control capital democratically. He believed our current treatment of capital (what capital entitles a person to do under our current system) was destroying people's lives and hope and autonomy.
But Marx and Engels actually dedicated several paragraphs of the Communist Manifesto to explaining why capital should not be destroyed during the overthrow of the bourgeoisie -- indicating that they did believe capital to be valuable.
