You might not realise this, but their trust fund does offer a service. Any investment always has another end. You have a person that has too many resources, and you have a person with too few. They are both making a deal where one rents out the resources. So although these kids do not "work", their money is working for them, offering other people rented resoures. That's how that works. Else there would be no return on that investment. This is very different than taxes. Not everyone needs to work indeed. But again it has 2 sides that are equal: you can only consume what you produce. This works on a large scale, but also on a small scale. Communism has shown that if you take away the small scale, and people are able to consume no matter how much they produce, that production goes down. Which is pretty logical if you think about it.
