Programmers that wrote this are not worth a penny because this thinking reveal shear stupidity and ignorance of the author. How does wage differential "prove" the intention?
An employer looks for a particular skill and submits an application for the visa. If it is proven that he cannot hire an American with that skill, the visa is granted. The relationship with state ends at this point, and the market begins. The law of supply and demand determines the price (wage). Since the supply of foreign labor is higher than domestic, the price is lower. That's all.
H1-B vigilantes, such as this author, are socialist that hate markets. They want the rest of Americans to subsidize their standard of living.,
