My perfect little world would be a world where everybody was rich and money was the least thing to be worried about. Nobody would succumb to poverty, nobody would be hungry, nobody would be homeless and nobody would have to work so grueling for the sake of money.
The only thing that would driven them mad would be the doings of charity. Those who did the most charity would be perceived and uphold as the respected and the powerful ones. And those who are lacking in charity would be deemed as the scums of the earth. Everybody would be racing to do charity. Everybody would want to clean public toilets, everybody would plant trees, collect trashes, feed the animals, take care of the elders and orphans, teach kids in school, build houses, clean the streets, and prevent any injustice, for free. Or simply be on their best behaviors.
Nobody has to suffer. No wars to be declared. No missile to be launched. No petty theft, no desperate people. Men were respected, women were appreciated, children were loved, and animals were petted.
What's the harm to imagine, because in reality, the world is too dire, too depressed, and too overwhelming for to deal with.
