And how would you takle that problem that isn’t plain “take from them and give to me”? Everyone of them had someone in the past do the hard work, and still today, you have people who succeed through hard work. Why not be the first of his line to build up wealth?
Because it’s immoral and it would be dual standards unless you take away from all who “didn’t earn it”, like disabled people or people temporary without jobs. Those also get money for basically existing.
There’s also the problem of incentives, if you encourage taking from those who have, you prevent new people from possibly starting businesses because why should they, if it will basically be taken away from them? Better to be jobless or do some minimal non-useful work and get money for nothing from the wealthy. You just move the problem from A to B but you didn’t solve it.
