As the lady that was interviewed stated, there will be families broken up, lost (cheap) labor pool members, and the reasons for not doing anything to curb the illegals goes on and on.
One thing people seem to forget when they spew the woes of the illegals is that when they snuck into the country they did so with the deep down realization that they could be caught and deported back to where they came from. Everify does not change that fact. So illegal beware a deportation could be in your future.
