Maybe the poor don't feel guilt, but the argument is deceptive. For the rich BI works just like a small tax deduction. Lets say a rich person pays taxes for $1000 and receives $10 as basic income. It just amounts to paying $990 in taxes. And the poor receive $10 BI and pays no taxes. As others mentioned it's just a redistribution of wealth. Make it look otherwise to not feel guilty is to deceive oneself.
