What I don't understand is why it's such a big problem to find employers who hire illigals?
It seems obvious for me that illigals are paid less than minimal wage. If it is not the case it just means that minimal wage is too low. But paying subminimal wage is already illigal, and any speculations about fake IDs just have no sence, employers know for sure that they are hiring illigals.
I think that such things like paying less than minimal wage can be found by good accountant even from balance sheets. May be not to prove that but start to suspect.
Actually, even this is not necessary. All of you know where illigals work, and what kind of companies hire them. These companies have to do that otherwise they won't be competitive on the market, but it is another story. I think, US officials are not silly than you, and they all know this as well.
The question is: why they know that, and do nothing or very little?
