There's a classic story that used to be told about Cambridge and Silicon Valley - both were good candidates for the tech boom but Silicon Valley won because Massachusetts allowed extremely harsh non-competes that prevented employees from freely switching jobs. The H1B visa vs. O1 visa argument is basically the exact same scenario - forcing workers to stay in specific positions hurts innovation and competitiveness. Once you're accepted into the US you should be free to participate in the labor market like everyone else.
