    In principle this can be a lot better than regular dating apps.

    Tinder doesn’t know if they were successful or not. They just know you stopped opening the app. In fact they are incentivized not to make matches that lead to marriage, because then you will stop paying.

    The government knows whether you got married and stayed married, and given the social cost of divorce, they are pretty incentivized to keep people married.

      I think they're more concerned about their fertility rate and labor force. A 0.87 total fertility rate for 2025 [1] is pretty bad.

        Western governments don&#x27;t seem at all concerned about this, unfortunately. They no longer represent the people, they represent the economy. And the economy is far more interested in importing millions of unskilled adult migrants from developing countries who are immediately eligible for debt, rent, mortgages, and low-paying jobs to prop up the GDP, rather than a crying baby that will leech on public services for 18 years beforehand. Culture, stability, safety, happiness, long-term prosperity and survival be damned.

          Believe me, if you ask the locals there they would mostly say the same thing about their government too.

            In Singapore?

            I think it is hard to find many places right now in today&#x27;s environment where people feel their government look after their interests. But you can definitely do a lot worse than what citizens of Singapore actually get...

            At the top of my head the only places I can think of where citizens get a comparably good deal are Switzerland, Dubai, Norway maybe Monaco (don&#x27;t actually know on this one).

              People who have a pronounced anti-surveillance stance will strongly object this claim.
