People will complain about anything and everything. What is extremely valuable about UBI, though, is that unlike traditional welfare systems where those who squandered it are often just those who are also the most pitied, there is no ostracism for using a UBI and no social isolation for it because everyone gets it, and those who cannot manage their money have no one to blame but themselves.

Today, the poor are defensive of one another to some degree, defending their "way of life" even when it is exploitative of social safety nets because they have to fight for scraps and every step of the process in getting such benefits is humiliating. It should surprise no one that once people have it, they are happy to blow it and stick an effective fuck you back to the society that ostracizes and criticizes them.

Which is one of the pillars of utility in UBI. It is a panacea solution to negating hostile poverty based cultures like ghetto. There is no more war against the poor, or active emotional attack for needing help. Everyone gets the help, and there is no vector for abuse through it, so those who are aggressive towards it or squander it are no longer fighting the man but are just fools who deserve no pity.
