I find it highly amusing our friends across the Atlantic asking 'why don't the Europeans do something'.
What happened when we questioned the fact that U.S. Corporations place themselves in Europe under advantageous tax regimes i.e. Starbucks, Amazon and therefore pay little or no tax here in the U.K. yet making a lot of money.
And regards to what they are paid, I seem to recall articles about pay grades at U.S. regional s.
It is just an attempt at protectionism and over hypocritical.
