The H-1B situation is also a problem for people who come from overseas to study for their degrees in the U.S. They get F-1 OPT, and join US companies that then cannot retain them because of the over-subscription of the H-1B.

It's also bogus to say that H-1B is more problematic than L-1B for body-shopping: all the well organized body-shops do massive amount of intra-company transfers.
