A possible solution could be to limit the personal (family?) wealth, fortune, possession, etc. to for example 100 million. That should be enough to live a luxury lifestyle and give your children’s children a ‘care free life’. Everything above that amount goes to the aid of the less fortunate, public and social improvements, energy transition, solving pollution problems, etc. (worldwide). In exchange you get a certificate with: “Congratulations you won capitalism!”
P.S. When you ‘cheat’ you get 1 dollar (or equivalent) and may start over. In addition and not exclusive of all possible legal proceedings.
P.P.S. The above is just an example to illustrate that there are possibilities. But this doesn’t solve all problems of inequality or everything else that is wrong on this planet.
P.P.P.S. Too many people think the have the possibility to also collect wealth above the 100 million ( or think they are entitled to an amount above that). They will protest and vote against any such solution. (I’m not talking about those 400 Americans from the website graphic).
