The eventual goal of a UBI should be to provide a basic sustainance income. But if that is provided right away, too many low-wage workers will just quit their jobs. Get $1000 a month for doing nothing or get $1200 a month putting up with a crappy job. It’s not hard to see that the freeloader effect will come into play. But start at $200 a month, workers won’t quit their crappy jobs. And the $200 will give them more options.

In my home town, people on social assistance often get help from five or more government and non-government agencies (sometimes it is easier just to find a low paying job). With a $200 starting UBI, governments can start scaling back some of these programs.
