Therefore, my current income is always, in a way, public money. We need to get approval from our future self before spending now. A bright future is only guaranteed if the future self agrees to the spending.

The first condition was that the recipient could exercise his veto power if he did not like the distribution ratio, and then, the ruler ensured that the giver did not have the money.

Most people think of fairness to vested interests between 50% and 70%. But, in some cases, even though the recipient had a veto, the giver had 90% and wanted to share only 10%. At that time, it was beneficial for the recipient to receive at least 10%, but by exercising the veto power, the giver did not have the money either. This is the moment of conflict between justice and rationality. People do not make decisions based on reason alon...
