The author notes that, “The idea of the UBI boils down to breaking the link between income and work…”
That’s certainly true, but the more serious problem is that UBI breaks the link between money and goods.
To grasp how significant this is, consider that the value of money is the goods it can buy. When money expands in relation to goods, as it would with UBI, inflation becomes inevitable. It’s not hard to see how inflation might lead to expanding the supply of UBI money, leading to more UBI inflation, leading to expanding the supply of UBI money, and so on.
And that’s just looking at one side of the money/goods relation. The other side would be monetary inflation that occurs by reducing the production of goods.
Many UBI advocates worry that without work workers won’t have incomes. However, there are many things which break the link between income and work. The most important is one that has always existed: simple process improvement.
Theoretically, the processes by which goods are produced can be improved so much that eventually no human labor will be required to produce any goods at all. This is precisely the utopia that UBI would like to enact on a small scale. But, as we’ve seen, the relation between money and goods would be unaffected. The utopia is therefore impossible to achieve.
