Most of the rentier class also don't have a "job". Dividends, leases, and IP checks arrive into their bank accounts and they are free to choose what to do with it. Invest wisely or blow it on vices. In concept UBI is closer to welfare than the tribal or Saudi model. Gamblers willingly go to their casinos. We willingly purchase Saudi oil. Since the government owns the means of production they are within their right to give it to their constituents. If fewer people gamble, buy tax-free cigarettes, or use less petrol that is less money the tribe and Saudis have to give out. UBI is not voluntary. The government extracts that cash from me in the form of taxes to distribute it. I cannot use fewer government services and therefore give less money to them.
