"A rich person, presented with a tax refund, will not necessarily increase his or her consumption. Instead he or she might well save the money...When the poor and lower middle class get cash in their pockets, they generally spend it straight away..."
If you think a basic income is going to have an adverse effect on savings/investment rates, there are plenty of ways to bump this up (sovereign wealth funds for example).
Please explain the mechanism by which this would work. Specifically, consumption of shoes and the number of people producing shoes goes up correspondingly. Some people quit working because their boss is a jerk. Where do the people building the new shoe factories come from?
