$10,000 a year and no opportunity to earn more in a world without jobs? That sounds terrible. How will you enjoy scraping by on $10,000 a year?
If this is going to work to the benefit of all but a handful of hyper-wealthy plutocrats, we need to move beyond thinking of UBI as a means of staving off revolution by a disenfranchised mob of people who cannot afford to eat, and see it as an opportunity for liberation by way of implementing it correctly from the jump. That means picking a level of disbursement above mere subsistence, and, more importantly, tying gains in disbursement to gains in economic productivity.
We continuously have to update our broken wage and welfare systems precisely because we never attempt to plan for economic growth. A low, static UBI would ultimately be worthless and oppressive, much like a minuscule, outdated minimum wage.
