Here's an idea to raise the birth rate that won't hurt anyone. Make degree inflation a serious target of legal reform. Most people use their college degrees in jobs that don't require college degrees for the actual work duties involved. Employers just slowly raised the requirements over time.

One reason the birth rate is so low is that most people have to reach their 30s before they're in a position to reasonably afford children. It just takes far too long for people to get established in careers, while human biological clocks haven't changed. We should be doing everything we can as a society to raise the income of people in their twenties. That's how you can actually raise the birth rate.

For example, we could set minimum wage and tax rates based on the level of education employers require for a position. If employers really want to require college or graduate degrees for a position, they can pay higher minimum wages and payroll tax rates.
