Because the other option is to starve to death.

That’s pessimistic… Food can be grown…

theft includes the net profits that are not shared with the workers

How businesses would innovate without accumulating capital? What happens if they suffer a loss? What would they pay their workers?

IMO it’s not theft, it’s just a price you’re paying for someone else to deal with risc possible losses while providing you stable income.

Not talking about reserch, marketing and realization of goods/services, that someone without capital can’t do on their own.
