More people declining to get married and/or procreate is the problem the government should watch out for. And instead of banning sexbots, they should make having a child easier. Make it so low and middle income people in their early twenties can buy a house. Make it so women can take maternity leave without setting their career back years. Make it so father/non-carrier parents get parental leave at all. Make it so a sick kid doesn't destroy a family's finances forever. Make it so women have adequate protection pre and post sexual interaction so that the risks of getting it on are not as high.
AI sex bots are far from the most impactful thing driving people away from having kids.
One of my friends wanted kids. She has a full time job in software and does side gigs like bartending. Can't afford kids, so she didn't have any. It's sad.
Meanwhile the ultra wealthy have more money than they can spend.
Nationalize health care. Basic income. Public housing. Enforce existing tax laws. Tax or prohibit bullshit like "I'll get a loan against my assets but that's not technically income so I don't pay anything". Break up monopolies.
The current global population growth rate is unsustainable. Are you speaking only in terms of country dominance/output? Globally, shouldn't we be encouraging less kids and contraception accessibility?
The current global population growth rate is unsustainable.
That's a myth. The current global population growth rate is dropping precipitously and is expected to hit negative rates within this century. The fertility rate per woman is at 2.3, from a peak of 5.3 in the 60s. That's barely above replacement level. At current trends we'll be at replacement level in a couple decades.
Income in societies (not only market economies, but all economies with some kind of money) is a function of one's relative power in the society. There's nothing absolute in one's income in money (as universal equivalent) connected to productive powers' development.
If that power is mostly held by government bureaucrats and corporations, naturally the conditions for population growth will not be very good.
And government bureaucracy and corporations like each other because they can have some balance of power while trampling everyone else, so government bureaucracy will not fight corporations to death.
