If they actually do any labor in those tasks, then yes. Labour doesn’t necessarily mean the bottom level stuff. Management still takes work. Setting up new businesses takes work.
Investment and ownership intrinsically aren’t really labor though. Just owning the company doesn’t add anything of value to anyone, and investing is more like a trade agreement. Should be honored, but not necessarily treated the same. Because investment does help create, and the owners presumably have done work to get from nothing to something of value in the first place. Ideally, anyway. This isn’t necessarily true in reality. Plenty of owners inherited, and why should they be entitled just for being born lucky?
Many projects take a long time to become profitable. The workers would starve until then.
Because of that, they need to borrow wealth to be able to keep working on the project until it becomes profitable.
The concept of lending wealth is therefore necessary.
Noone is gonna accept the risk of lending out wealth unless they expect some gain, some profit.
Therefore the workers promise to not only repay the lent wealth but to also pay on top of that, perhaps a share of the project’s profit.
Hence the concept of profitable investment is necessary.
