What about the other side of some of these things, UBI in particular? How do you account for inflation and higher costs for goods?
Example (and I know it's overly simplified): minimum wage goes up to $20/hour. People have more buying power, so they buy more (demand increases). Costs of goods go up. Buying power is reduced. Another call to increase minimum wage is issued. Cycle repeats.
How do you reconcile these very real consequences? Can we really say that the benefits outweigh them?
Answer is: they may very well have more benefits, but we can't know without doing them - and the consequences of getting it wrong could be permanently damaging.
