But, practically, the planet cannot support anymore than just one child per couple
Actually, you'd need 2 children per couple just so that population stays stable (and that's incorrectly insinuating a 0% child mortality rate).
To reflect this and combat the 4-2-1 problem (one child having to support 2 parents & 4 grandparents), couples where both partners are only children are allowed to have 2 children - ie: there are limits to the effectiveness of a 1 child policy, eventually you'd have an economic breakdown due to demographic stress. China's policymakers aren't complete idiots, hence the shift in policy.
That said, i'm still not convinced the one-child policy is as responsible for the lowering of birthrate as much as chinese officials claim: the introduction of the policy lowered birthrate from ~3 in 1980 to 1.8 in 2008; compared to the drop from 5 (in 1970) to 3 in a decade, caused by policy (essentially education & advertising, not legal cohercion), and increased standard of living.
Furthermore, the enforcement of the policy (while harsh & inhumane) is uneven at best (hard to control in remote rural areas, especially since officials often look the other way), and don't forget that multiple births (twins and such) don't count: while you can't exactly decide to have twins, fertility treatment is known to increase the chance by a lot. Turns out the proportion of multiple births doubles since the introduction fo the policy...
We just need a good old fashioned war in which millions die...Sure it's not the most humane option but hey, I can't be bothered thinking a real solution at the mo'
Let's say a nuclear WW3 with 700 million dead - not quite a nuclear holocaust, but a limited nuclear conflict, certainly a decently sized mass slaying of tons of people (who'd much rather have lived their life in peace). Great, we're back to 6.0 billion people on earth instead of 6.7 billion, except now a ton of countries have been thrown back in their standard of living & medecine, so that having lots of kids again becomes a decent option for investing in your retirement.
Btw, this postulated WW3 has roughly 10 times as many dead as WW2, so it's not like i'm being skimpy. I'm liberally doling our fictious deaths here.
All that does, is throw us back to a late 1990ies population figure, while simultaneously kicking us back into a 1900s standard of living, and subsequently higher birthrates. The problem of overpopulation just became worse, especially since we can usually observe an additional bump in birth rates after massive death events.
Tax extra children is the easy solution
The nations that have population problems are generally poor. Taxing poor people does nothing. As a counterpoint, if us rich nations want to have more children coming out of well-to-do homes (and we do), we should consider lowering taxes past 3 children, and do it in a way that affects middle-upper class households (say lowering income tax, or basis of calculation of income tax in households with 3+ children; or make child expenditures (especially medial & educational) allowable against income tax)).
Savings in low-income households would be negligable, while they could be substantial in middle-upper class households, and tip the balance towards a 3rd or 4th child - and world-overpopulation issues aside, us western nations generally want MORE children out of our middle & upper classes.
Actually I can't understand why so many people are saying no.
Because it's a massive government interference in my human rights; and the better solution is to figure out how everyone can have a decent standard of living. Not only does it cause comparable birthrates (Europe/US vs. China) without forced abortion, gender biased abandonment / infanticie, etc.. it has the sideeffect of creating a decent standard of living all over the place.
I don't see why you'd want a law like this at all, especially since it's a very narrow stopgap measure that adresses birthrates only, while causing a whole bunch of other problems, and doesn't adress education, wealth, safety, etc...
Humanity is not going to end because there are too many humans. Does that even need to be said?
No, but it's a neat way of saying it
