    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 They no longer represent the people, they represent the economy.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.

          The same immigrants that started 50% of all American unicorns?

            Unicorns that are now destroying America, its democracy and threated to take rest of the world along. So, it might not be all that great argument.

              You think successful tech companies are destroying America?

                Yes, I think Thiel, Musk and the rest of them are deliberately trying to destroy both democracy and America as such. I think so, because they are openly talking about it.

            People forget that e.g. Andy Grove, Intel founder, was a refugee from the Nazis.

              And Elon Musk is an illegal immigrant from South Africa.

                And importantly because a lot of the opposition to immigrants is generally racial, Indian founders have founded something like 20% of all unicorns in the US while being only 1.5% of the population.
