1.) We'd have to implement it so that starting somewhere on the pay scale, taxes increase so that by some point you pay back to full $10k you received. Naively: $25k income you pay back $1000 of the $10k in taxes at $50k, pay back $2500, etc. That way you, making over $100k, essentially get $0 basic income by the end of the year. 2.) You probably have to say "everyone over 18 gets $10k, each child up to 3 per family gets $2k"...or something similar. Getting $10k per child creates some crazy incentives. (2010 there was roughly 70m people under 18, so it's only $2.38 trillion! ;) 3.) You can probably remove a ton of welfare programs if you do this, but not all. You can't completely remove the safety net, but a lot few people should have to be serviced by said net.
