You seem very certain of this.
You simply don't care that many other countries around the world have done it for decades with good outcomes?
For some unexplained reason, the US (which you yourself said is the richest country on earth) is different and the results will be disastrous in the US while they are not elsewhere?
I honestly think you're not seeing the big picture. If minimum wage goes up and gets pegged to inflation, low-income earners will simply take home a bigger portion of the enormous wealth that is created in the US. The richest class will take home less. That is precisely what happens in at least 20 other developed countries around the world, with excellent results. There are very few wildly rich people, and there are very few wildly poor people. Mostly everyone is in the middle.
The US could do exactly the same thing with exactly the same results, you just don't want to, because you're happy for a class of people to exist that barely survive to serve you.
