And, if we attempted to go for this in the US, how much struggle would there be to both implement the minimum wage and also remove all of the other programs such as welfare, food stamps, disability?
The system is very well established and you couldn't just remove each part in a single step. Each program that gets removed would need to be eliminated one by one.
Overall, I think that a basic income is the cleanest, fairest, least game-able way to help the lower class. I just don't see it happening in our current political climate.
