Some paid down bills, or invested like you did. Others were of a more short-term consumerist mindset. This is one of the reasons I am skeptical of UBI proposals, too. Will people build, or coast along? It depends on the person. Producers or plunderers? Makers or moochers? And such redistribution will be funded by either ongoing inflation or more taxes on the producers. It's a perverse incentive structure whenever anyone tries to manage such a complex system where the parts are human beings with varying morality, time preference, and even taste in style.
