Glenn makes a reasonable point about the pseudo-proposal for universal pre-k:

“There’s another way of looking at this: as an overt sop to the teachers’ unions. What a great way to expand the ranks of the credentialed, licensed, and dues-paying members. And don’t forget tenure.”

Good point.  It wouldn’t just expand the teacher ranks, theoretically it would bring in lots of younger dues-paying members.  Growing the paying-in cohort would extend the life of the ponzi scheme of state/teacher pension retirement plans for many more years.

Of course the right immigration policy would do this for social security as well.  I say let in anyone under 30 who can get a job on the books.  Wouldn’t hurt housing either.
