Perhaps it’s unfair to people who want to have kids but can’t that IVF is so expensive, but really, there’s one thing that affects birth rate more than anything else: cost of housing with decent nearby amenities, infrastructure etc. If housing were cheaper, people would have more kids… Simple.

So if you want to solve the social equity problem, subsidize IVF. If you want the birth rate to increase, knock down the barriers to entry and high costs in the housing market.
