Well considering US unemployment is 4.4%, the reason these people get hired is because companies must do this in order to get work done.

It is similar to marajuana use: despite the laws criminalizing such behavior, a black market will always appear to accomodate the demand. Of course, I support decriminalizing marajuana because it would benefit us overall to get out of the black market buying/selling operation.... and I feel the same way about immigration.

Of course, if we had an economy with extremely high unemployment and a decling level of GDP then we would not have this pesky problem of people entering this country and taking jobs from all this work going around.

Perhaps our government could take bold steps to create that, and then we might not have to keep living this horror.
