It would probably require either isolationism or a true global government, and neither of those are feasible or desirable. That's undoubtedly why our economies tend to be mixed because basic income in a place like America would require too much sacrifice to sustain in the long term.

Before an actual post-scarcity society, we will need government provided basic income, which is simultaneously a scary thought if we don't solve a bunch of other global problems first.
