Well profit can be defined as money_in - money_out therefore the maximum profit is the least amount of money_out with the maximum amount of money_in. So let’s assume that the minimum amount of money_out is 0. So it becomes a question of what is the maximum of money_in well currencies are generally just numbers. So we need to know the total amount of matter in the universe and the value that an organization of that total amount can represent. If the universe is infinite then infinite profit, if not then there is some number. However, at this point we delve into the zone of philosophy as we might need to take some of that matter out to have some witnesses. But still might not buy you a house in 2024.

Tendency of the rate of profit to fall

In case you want a serious treatment, for nominal profit:

For real profit, labor productivity must put some limit on it somewhere, but I have never seen anybody look at it.

Either way, “profit” is not something you squeeze out of society. The nominal one can’t be unbalanced, and the real one is hard to even track.

You may get some better answers if think in terms of wealth inequality. But that one won’t appear on the coarse level of the wikipedia article.

You’ve discovered capitalism’s super hidden secret; infinite growth on a finite planet is impossible.

Huh? At any point in time, even if there are 2 humans left in society, and one human procures something and gives it to the other guy in exchange for something more than what cost him, it will be profit?

In a sense yes. Once a company has captured the entire (global) economy, including banking, it would control who to give credit to, who to employ, what to pay them, what their own products are priced.

They could at most reap as “profit” what they give out in credit and payment.

There may be sub-limits for capturing entire industries.

There’s an actual limit to profit, they are called profit margins and different industries have different profit margins.

Yes, there is a limit.

First, you need to look at the difference between 1. money and 2. value.

That theoretical one rich person (or company) might own all money printing facilities in the world, and therefore can make endless numbers. That is money, not value.

There is theoretically no limit for the money. But this is meaningless, because this kind of inflated money would be valueless.

The one rich person might own everybody else, and all their belongings, and all that they can produce.

That’s all the value then. That’s your limit.

Once one person has all the power, they de facto have all the wealth. Slaves don’t own anything.

Maximum profit would be achieved by charging the most for the least stuff. And minimizing the cost of that bare minimum. You can do that by eliminating competition so that your prices are the only option. You’d end up with something like feudalism.

But it also depends if you target maximum profits as compared to the population, or maximum profits over all. If maximum profits over all, you’d want to grow the work force as much as possible, maybe colonizing other planets or inhospitable regions of earth.

But maximizing the value of those profits to you requires development to get you more value for less resources. Being a king hundreds of years ago still didn’t get you decent plumbing. So you’d want effecent ways to maximize your pleasure for the lowest cost. Some brain computer interface could be useful there, so that you can create full planets more cheaply.

What happens after all of humanity are enslaved as software devs for the god kings personal virtual reality, I couldn’t guess.

One way historic economic systems prevented total market capture by family dynasties was large families.

A big family dividing a concern will eventually sell it, break it up so it can be split.

With smaller families this division will take much longer, and with corporate personhood we are in a new weird self perpetual bureaucratic regimen

Technically, money is just a number on a ledger. Practically, there’s a finite amount of wealth in the solar system, much less on earth, significantly less accessible to humans and only a slim amount can be taken from the working class before people start starving. We already have little enough that the population is going to start contracting.

Theoretically? I’d imagine it’s equal (or close) to the difference between global money supply and global money supply but I don’t think that’s what you’re asking

absolute or percentage wise. in absolute terms all of the universe. in percent terms nope because like gambling allows for infinite profit. ie guaranteed profit on rolls that will most times not result in any loss.

There’s a limit with any particular set of tools and labor, but a universal limit doesn’t exist, no. Profit comes when you take money and use it in a more productive way than letting it sit under your mattress, and there’s no theoretical limit on productivity.
