The best reason for implementing basic income is so that we can abolish minimum wage and manufacturing shoes can actually be a competitive business here. Why should a business that makes shoes stay in the country if they can ship the jobs to Asia where they can make shoes for much less than the minimum wage? (This is just an example, but you get the idea. And I don't believe we should abolish min wage yet)
Sorry, communisim plus capitalism won. Look at China. Democracy is failing because people still think that UBI is some sort of dirty welfare scheme that gives everyone a free pass to retire tommorow.
