- I think you mean destroying the social net and upward mobility. Note that we do "half as well as Nordic countries" In Norway, half of all children are born to unwed mothers. Sweden and Denmark have similar numbers. The issue isn't marriage, it's our cultural values. We've devalued education, and honestly, we've never backed up our claims of "family values."
If we truly valued families in this country, we would have parental leave protections for employment like virtually every other country on earth does. We would have universal health care so that families could afford to move or change jobs without jeopardizing the family due to a family member's health condition. We wouldn't be attempting to shred what social safety nets we have, like Unemployment Insurance or Food Stamps, paltry as they are.
Instead, we value the Almighty Dollar over all of these things, and tell people they shouldn't be having children they can't afford, all while making contraception and abortion more and more difficult to get if you're poor (the wealthy have never had problems accessing abortion services, even back when it was illegal. Read up on abortion in the 1950s sometime).
