That's convincing evidence.
So now it's Bush, the Senate, Big Business in general, and Wal-Mart in particular that are all bad, and unions that are good?
Further, the "small landscapers and roofers" you defend aren't competing with big businesses (which you claim use illegal labor), so what forces them to hire illegals?
Self interest. As I said before if your competitor cheats, you cheat or go out of business.
What would force them to not hire illegals? Enforcement of the present laws by the present President with the support of the present Senate.
Next time Bush tells you the "illegals are doing the work that Americans won't do" remember to finish the thought at half the wages to which Amerians are accoustomed.
