As far as inflation goes: think of money as a signalling mechanism, not as a reserve of wealth. This is true for the wealthy, and as the marginal cost of producing goods drops, it becomes true for more and more of the population. When factories can more flexibly adjust production, you'll find increased demand for, say, iPhones, and decreased demand for, say, TVs, will shift production and damp the price inflation.<p>Secondly, consider that an economy without a UBI yet with mass unemployment will suffer a liquidity trap. This is a more efficient way to fight that than QE (which I'm not criticizing as it was the best tool available for the times)
