So. That’s the point. Or one of the main points. At least, as far as the people actually setting republican policy is concerned.
They need cheap (read, unskilled, uneducated,) labor desperate for low-paying shit jobs. The easiest way to get that is to force young women who aren’t ready or very incapable of having a child to have children.
This creates a desperate single mother struggling to afford basic necessities; and likely a child without any financial support as they become working age adults- and similarly desperate.
You’ll also notice they’re all for the tough-on-crime stupidity that locks people up for shit reasons and then forces them to work in the only constitutionally-approved form of slavery.
That it just happens to affect more minorities is just a bonus.
