As a new parent, I'd argue that we need to incentivize having children a little more in this country. It's just too expensive and childcare is too demanding today, compared to what it was for a lot of us growing up (imo). Too many in their 20s and 30s don't have the money and/or the desire to have children.
So yes there *could* be some advantages to some liberal policies that emphasize greater parental leave or higher child care tax credits. BUT, we're also sitting on high inflation that hurts the spending abilities of new parents, and that's not democrats strong suite.
I'd rather see America figure out how to entice CURRENT Americans to have more children.. instead of just taking in every countries poorest, weakest and desperate to fill the gaps.
