so we shouldn't pay people to stay at home because we'd have a population explosion? Well thats easily solved, pay for say 2 kids and then no more.
But actually I believe that people DO generally want to work. And most of us WILL be working pretty much til we drop, there will be plenty of time to pay it back.
We should pay a parent to stay at home if they so wish in order to give parents the CHOICE. The choice of going back to work or staying at home for a few years
otherwise, whether or not you can stay at home with your kid is down to how much your dp earns, bascially. Why on EARTH should that be the case? So if you happen to marry a dp with a good income, who hasn't had any disabling accidents, who does not face systemic discrimination for whatever reason, they oh yes you can stay at home and bake apple pie, but everyone else can just use childcare 8-6. Thats not fair at all, IMO.
And why on earth NOT give the child care creidit to those who qualify to spend as they wish? Why not?
Its not about whether parenting is a job or not really. Thats a bit of a philosophical question. If you don't like the idea of people being paid to look after their own kids, fine, call it "SAHM benefit" or something. But it would make a lot of women a lot happier and I don't think it'd cost that much really- tax credits are, after all, the taxpayer subsidising business paying crappy wages.
