You should apply some second order thinking on this argument.

In the welfare days, those that were in more need were women with children where the man ditched the family. So more effort and money was applied there which seems totally reasonable.

But it also incentivized men to leave their families to qualify, and they did in high numbers.

These type of things made to correct something in the past also have a tendency to incentivize something bad in the future.

This is part of why these things are so difficult in practice.
