Yeah but the number of H1-Bs per year (65000, some of which are reserved for Chile or Singapore) isn't set by the market, but arbitrarily by the government. Why is that number set in stone regardless of economic climate? It was obviously more than enough during the 2009-2012 slump, when there was no lottery, but not enough now.

>the salary needed to get an H1B will fall to zero

Except the job market isn't limited to immigrants, and not all immigrants are equal in quality. The bottom isn't zero, it's the average wage for U.S. citizens, because otherwise you'll drive down the wages for U.S. citizens.

You will get H1B shops opening in remote, rural locations and then using the immigrants to consult in other, more expensive locations. The goal is to get qualified immigrants to work directly for companies at those company locations.
