The top end of H1B has been great for America. In the last few decades, there has been growth of abuse of the program to get mid level talent at below market rates which really hurts the middle class in America. People need to understand that most reformists don't want to get rid of the truly exceptional immigration to the US.

Agreed, however the top end usually comes to US to do masters and then tries to get job using H1B. If this is where to be instated in this form, it almost precludes any fresh college graduates from getting a shot at this.
