Capitalistic Economy

How are wages, rent, interest, and profit determined in a capitalistic economy?

You can group all of these questions in one post, or multiple posts in one thread. They don’t each have to be a distinct discussion.

I got a one-bedroom apartment for rent. How much you wanna pay?

Through supply and demand of the good in question(labor, housing, money and goods in general respectively).

You’d think it’s more complex than that, but it isn’t really. And “determined” isn’t really the best word I think, because it implies that someone is making some kind of executive decision, or figuring something out that was already the case.
