It's irrelevant how much they want us to make babies (Western Europe), as unless real estate prices plummet to levels affordable to young couples without rich parents, you won't see birthrates in the west go up without heavy immigration from developing nations.
They can't expect to have rising birthrates that would sustain the pyramid scheme of the welfare state while at the same time treating real estate as an investment vehicle that goes up faster than wages, squeezing the younger generations out.
Either the welfare state in the west will collapse or the real estate market will. You can't have both going up at the same time.
