They kinda have to. If I'm so productive at producing food that I grow enough for 2,000 people, I have to find 2,000 people to feed. Or the land sits fallow and I get nothing at all. There is a lot of wiggle room at the margins, but overall it is hard to get away with producing more stuff and warehousing it.

We'd expect to see a bunch of silly jobs where people are peeling grapes and cooling the wealthy with fronds; but the capitalists can't hoard the wealth because they can't really do anything with it.
