Explain, please.
The legal system makes them indentured servants in all but name.
Compared to regular citizens:
1. They have no effective freedom to quit without finding another sponsor. Citizens have the freedom to pursue employment as they wish.
2. Should they wish to pursue a green card, they start over with each sponsor. Citizens (by birth or naturalized) do not have this issue.
3. A greater incentive exists to prioritize manageability over competence. A competent guest worker would look for other opportunities, while a minimally competent (or incompetent) guest worker can be controlled more easily.
4. The prior qualities, combined with unchecked fraud, suggest that they are a market distortion caused by government regulation.
Remove the guest worker programs, repeal the 1965 Immigration Act, and observe a restoration of a market based on actual competition.
