IMO the obvious solution is a) don't tie the visa to an employer and b) increase the earning bar. This way the body shopping model breaks. Also in the current system workers tied to an employer have less leverage in terms of demands/wage negotiations, and tend to stick around for a long time, so this part of incentive from the hiring managers perspective will go away.
