Well within a year we would have poor and rich again. People who have money are good at managing money people who do not have money suck at managing it.
Within a generation or two it would look probably exactly like it does today.
I would bet that less than ten percent of people would use the money to make money and be better off.
Though I bet most everyone "thinks" they would be better off.
Then you have to add this.
How many people would just stop working at low level jobs because they had money (for a while)
How much would a head of lettuce cost since fewer people would want to bother picking it or growing it?
I wish everyone had to play a game called Ultima Online. There is an economy system that sometimes gets screwed up. Sometimes by scammers sometimes by game masters.
Some items were worth millions and people were willing to pay millions in game dollars for rares. The Game Masters in all their wisdom thought everyone should have a shot at the rares so they made them easy to get. Can't give them away now because there are so many. They were worth something to someone when they were rare but now that they are common no one wants or cares about them.
When gold was hard to earn it sold online for 25 dollars per million game coins, the game masters decided to make gold easier to earn, now you can buy gold online for $2.50 per million. Great huh? wow easy to buy gold, problem is, things that used to be a million dollars are now 20 million dollars so it actually cost more
so take all the money, divide it by the people and watch the nightmare begin
