The problem with "basic income" as I see it is people's ideas about what a proper standard of living is completely subjective. Should a basic income cover an apartment, or a house? Should it cover cheap food or expensive organic food? Should it cover technological gadgetry, and if so, how much? What type of car is "fair" for someone to be given? How do we ensure people's standard of living doesn't continue to increase. Will we not always have someone with more money to compare ourselves to? It's the nebulous definition of what a "basic income" should be that has me worried about the whole concept.
