Way to go
Let's make those pesky illegals as exploitable as possible!
What happens if the cunning little blighters use forged id? Do all employers have to become id experts? Of course not, once everyone's got a new unforgeable personal id card there'll be no problem. And, as an added bonus, the government will know exactly where everyone's working all the time!
Oh well, at least we've got plenty of spare prison space available for all these new criminals.
