They practically do that now for a large number of families.
The families to know how to game the system and decide to do so, are okay with giving up responsibility and expense of child care to the programs.
Some folks qualify for and need these free programs for a few months or years, and that’s fine, but at some point, the programs will begin making decisions for your child as though he or she was their child. The overstep may be disguised as ‘healthcare’, i.e. meds for hyperactivity, counseling for birth control or sex re-assignment w/o including the parent in making the decision.
Welfare should be limited to no more than 6 months twice in a lifetime.
They game the heck out of Christmas. They sign up multiple times for all the free gifts they can get. Remember that next time you see a gift tree at the mall.
