Yeah good ideas. The hope is that the governments, more hungry for the revenue from sales + property taxes will capitulate, instead of forcing such stupid laws.
But on the other hand, if Home Depot feels they can make a profit even under such dumb restrictions, you can't fault them for staying.
What would be really smart is if Home Depot somehow got H1B visas for these guys and employed them legally. Then no more day workers bothering people, and Home Depot could make even more profit by managing the workers themselves and taking a cut. Plus since the workers are hired legally and not under the table, they'd pay their share of taxes, etc. And the government could go scratch.
I think anyone that hires the illegals should be arrested. Also, before inspectors issue approvals or certify home improvements/additions the home and the contractor must prove that no illegals did any of the work. If they can't then everything gets ripped out.
