Prices of things are becoming absolutely insane. $800+ rent, $30,000 cars, $10 sub sandwiches, etc. It would be nice to do a 3/1 split and cut everything by 2/3. Then we would have $266 rent, $10,000 cars, and $3.33 sub sandwiches. Wages, debts, everything would drop to 1/3 what they are now. It would also make coins useful again since a vending machine soda would be 2 quarters again.
How is 11 trillion any better?
If you want to actually bring that to a number people can grasp than small amounts would become impractically small. Like you would need to deal with 0.000001 and 0.0000001 dollars and stuff.
