>What about people with partners that are non-citizens? I know a lot of people in that situation, myself included.

Marry or become a citizen. Or don't, depending on where you live this may not be a problem.

>Double income households are penalized outside of marriage.

Yes, because POV from the state is that you are 2 unmarried people. If you want something that is like marriage but doesn't have the same name (ie civil union), I am all for that.

>We're not having many of these now. Population growth is now driven mostly by immigration.

Which in term leads to population decrease from the other country. So not directly a solution.
