>Corporations are social by essence, and on a much bigger scale than anything that came before.

Corporations are transactional by essence, not social. Any relationship within or with a corporation has the singular goal of making the corporation money. Food deserts exist because corporations aren't social. Supermarkets and stores aren't there feed the community, they sell food only to those who can afford it, and only for a profit. If it comes down to it they'll station cops outside the store with shotguns to keep the poors away and let the food rot on the shelves because that's how capitalism works. That's the exact opposite of everything socialism is supposed to stand for.
