Is it? Why? In myth, Procrustes either stretched or amputated people's legs to make them fit on his bed. Basic income forces a minimum wage, but not a maximum, so I don't think the comparison is apposite.

Since it's supposed to replace current welfare, chances are there are people who would get less money with the UBI than what they currently get. In that case for them that will indeed feel like a cut (pun intended)

And if everybody gets as much or more than what they currently get, then it's fiscally irresponsible.

And it's fiscally irresponsible to create a bureaucracy to fit the welfare exactly to the needs. A conundrum.
