I'm not convinced that "laziness" is a weakness of human nature. Businesses are ultimately a way to specialize production without central planning. Allocating some people to bake all the bread in a factory frees up other people who would otherwise have to spend an hour or two every day baking bread. Or from a market perspective, you're willing to pay a premium for not having to put in the labour. Businesses certainly can be exploitative, but I don't think all or even most of them are by nature.
