1.) Corruption - Washington DC, the Bush's, and the Clintons sold out America and Americans for foreign money.
2.) Globalism - The benefits went disproportionally to urban business centers while the costs were mostly borne by rural areas and hubs of manufacturing.
3,) Offshoring - Transferred knowledge-based competitive advantages, and the industries built upon them, to overseas competitors.
4.) H1-B visas - Constrained the upward mobility of working class Americans educated in American universities by forcing them to compete with foreign college graduates educated for less money overseas.
5.) Foreign Students - Most foreign students come from wealthy families that can afford to pay the full tuition rate, putting working-class Americans who can't afford to pay full tuition at a financial competitive disadvantage.
The American Goverment sold out the children and grandchildren of those who defended freedom in WWI, WWII, Korea, Vietnam, and Desert Storm to rich foreigners. America has been for sale and Americans have been sold out by their own Government.
I hope the iPhones, Nikes, and cheaper IT workers were worth it. America is being economically colonized, and intellectually pillaged, by foreign nations, including China, India, and Persian Gulf petro-states.
