So, there is still nothing stated in terms of how much of a US firm's business is done in the US and how much elsewhere.
And those GDP dollar values you're concerned about used to be referred to as the high American standard of living. and the lower Asian standard of living. Would you like to see all compensation in the US brought down to Asian levels?
The reality is America is no longer an island of manufacturing hegemony. We had that power after WWII since the other prominent manufacturing giants of that era (Japan, Germany, UK & Italy) had their factories leveled.
There is just no way we can continue to have a standard of living head and shoulders above others any more. We can quadruple our wages and then the price of goods & services will also quadruple. And then our exports of finished goods will nosedive.
So yes, the reality is that all industrialized countries will level out at similar standards of living. Like it or not.
