IT benefits businesses.
As the greedy sons of bitches sit in their back offices, counting their profits on the backs of the tax payers, that are forced to pay for the titanic, government sponsored disaster.
It's really quite simple: All the President wants to do is register illegal aliens with the federal government so they'll pay taxes, let them work for a few years doing jobs that Americans won't do like picking produce (after these jobs have been posted for 60 days FOR Americans but haven't been filled), and when their guest-worker permits expire, they'll have no choice but to return home.
But Congresscritters and hysterical FReepers would rather have the illegals still wandering around on the streets and getting paid under the table, sending most of their income back home to relatives in Mexico.
