Is it not a bad thing in the general case? People who produce net positive value for society subsidize the unsustainable reproduction of those who are a net drain. It is a very sterile perspective, but reality doesn't care about empathy, and you can't feed people with good feelings.

I do not agree that contribution to society is measured in dollars.

Did anyone say it’s a bad thing? About 15-18% earn at that threshold of under.

With the assistance, though, the amount of net is about the same as someone earning $80k-$100k but gets no assistance at all.

This sounds like you are saying it is a bad thing.
