I'm with you on both the immorality and consequences of transfer payment programs. That term is too sterile anyway, we're really talking about theft.

UBI makes sense on two grounds...

1. It's a feature of a voluntary system along the lines that @dantheman has proposed.
2. Its enactment truly is a replacement for every other "transfer payment" program, thereby making the system more efficient and lessening the overall burden to those from whom life is taken to subsidize.
