it's because the capitalists can't outsource everything. the maintenance of the homes they own and the infrastructure they use, the people who raise their children, cook their meals, clean their laundry, bring them treats, rub their backs, who guard them while they sleep... none of that can be sent elsewhere.

that's why they are freaking out. because they can't do shit for themselves. and if the price of labor goes up, the calculus of their fiefs might shrink.
