Ellaborate please or link that strength your argument about why it is more expensive if both parents are working
Total paid on childcare is higher in a family without a stay at home patent, though the two earner family generally will have more net disposable income (After child-care)
If you begin to optimize social and political decisions on the basis of having more tax payers, you'll get weird results. For a second example, cutting reproductive education funding in schools will lead to more tax payers (though arguably tax payers who pay less, so then the question becomes are you optimizing for tax payers or for future taxable income in total).
Do you have a citation for this? One with "cutting funding" in it and not the generic comparison between Somalia and Germany.
Your primary fallacy here is that you think you can always "mince the meat back". You usually can't. It doesn't work that way.
Actually, it is a correlation between educated women having educated partners that know how to use contraceptive methods. Educate all men and women's education will be less relevant. Or stop any education of men, contraceptive methods will decline and fertility grow.
> Is this, in the long run, also good for the taxpayers?
It all depends. Is it good for "taxpayers" that humanity does not go extinct? Is taxes the only moral compass for our society?
Each time someone mentions a social advance for our society there is a big reaction against it because "costs money". Yes, it costs money, and it is money well spend in the citizens well being.
Is the legal system, schools, the police force, firefighters, etc good for taxpayers? Yes.
Does it costs money? Yes.
And that is why there is taxes. To pay for our needs.
Quality is more important than quantity. More educated people will produce better product and improve everyone's lives. Not saying that denying 50% of population a chance to live their lives as they want is plainly wrong and immoral.
Not everyone wants to have kids and family. Some will work, some will stay at home. Same goes for men btw.
Child care is subsidised heavily by other taxpayers, but only government childcare - get a grandparent round and there's no tax break. The tax system works hard to discriminate against single parent families too (two people with two kids on total £80k pay a marginal tax of 32%. One person on £55k pays marginal 60%)
