It would be as great if European and others countries put a 25% tax on all revenue Google, Facebook etc. generate in their countries.

Especially tech companies making their money from ads and such provide very little real value and just drain massive amounts of money and transfer it to the US economy.

They generally have way more employees in the US relative to how much money they are making domestically.

I agree on both points, but my point was that there are people aware of outsourcing and working on curbing it too.
