The good news for homebuilders, versus software firms, is that they don't have to go through an interview process and H1-B visas.
No, our homebuilder friends just illegally use illegals who illegally walked over the border. Or "used" I should say, as the millions of illegals who used to build homes are no longer needed.
But for the Microsofts, etc of the world, who want to import smart yet cheap people (on planes) to replace American workers, check out this video. Nice to see the system being gamed so easily.
Get the feeling that corruption in our modern American society is everywhere folks?
