If that $22 billion was money being repatriated back into the US economy from overseas, then great (I wonder if these sorts of transactions are included when working-up the 'trade balance' statistics?).
Besides, if you check it out, I think you will find that the British are still the largest foreign investors in American commercial property, like shopping malls and other commercial/retail developments, etc. but I don't see anyone writing editorials about how this is a bad thing for the country or how this might unduly increase the influence of 'Anglophiles' in our culture or society.
