You have to be a really good capitalist. If anyone could do that, they’d bid up the price of employees until the companies can barely turn a profit. And at that point, the skeletons barely help.
Also, they work 24/7. Even if they worked for someone else, they’d do at least double or triple shifts, depending if they’re 12h or 8h, netting far more than 2sp.
Only if you send them to work somewhere else and have them give you their pay.
