The ways to build the system you desire are simple; the political challenges though are insurmountable. This isn't rocket science. However, there has been no substantial legislative change in this area in over 30 years. The current morass of H-1B, PERM etc. is a carefully engineered compromise to keep all demanding factions - the restrictionists, the capitalists, the left and the right, acceptably (un)happy.
