We already do that. Many of my coworkers at Target are on medicaid and SNAP and get child care assistance and they will be, perpetually (well not so much the child care part).

We just also make them work until they're 70+ anyway.

Or in other words: we make them work. If we didn't we'd still need someone to do the work, only it wouldn't be your current coworkers. And we'd have to tax that person severely, so we have enough money to fund the early retirement of your coworkers. I'm not sure that person will be happy.
