Every time you try and counter that argument, one of them points out to you that the guy on the H1B visa working in the cube next to him got his Masters Degree for free in his home country.

and here he is.
Because his home country couldn't give him gainful employment, so he had to undercut the wage structure in this evil capitalist country by undercutting wages on an H1B program.
When I worked in Japan (1988-2002) as their equivalent as an H1B employee, the companies had to pay us a PREMIUM over the locals as a condition for the visa. Imagine that! Fewer foreign workers but happier ones who didn't resent the natives and, instead, appreciated the opportunity.
Further, I actually raised the wage level on my Japanese counterparts by earning that wage premium, encouraging more of them to go into similar work and forcing me to get better every year so I could justify that premium pay.
