Mike this nails it, not only in US, but in the rest of the world too, thanks for posting.
I think it wil happen more or less naturally, upon the issue of continuous stimulus, to a level where all have disposable income.
It doesn’t matter if the bulk of early stimulus goes mostly to the rich, as long as everyone sees some disposable income, in addition to what they need to live.
The first country to do it will see a leap in the market price of their national currency.
Then all other countries will follow, to maintain the prices of theirs too in comparison.
