As a category, American companies are the most profitable in the world, so they’re doing something right.
Or is the profitability less about agility as per the GP comment and more to do with employee manipulation(for lower wages) and political sway (for lower taxes).
Hell, given where FAANG pay taxes, are they even American?
This may change in the case of Amazon with its fulfilment centres, but see above comments re: Manna.
