US don't trust education system provided to foreign students. That's why they need to hire people from outside the country who are educated in different system. If they did trust their education system provide to foreign students, you'd be the first one to get h1b and then the people educated in different system. All the money you paid, your contribution to the American economy doesn't mean a sh!t anyway. Thats the way it is and thats the way it always be.
