So, the fact that their employee had to commit a crime to get into a position of employment, and are continuing to commit a crime in order to maintain that position of employment, and the employer's knowledge and acquiescence of such matters not? We've been talking about getting rid of incentives that cause people to want to enter this country illegally. The employer that will hire them without concern for their legal presence is that incentive. If you refuse to get rid of that primary incentive, then what is the point of the rest of this? If hiring a prison escapee was even cheaper than hiring an illegal alien, would that also be alright? Both of them are someplace that they are not allowed to be, by law.
First off, it isn't the employers job to enforce the law. If Person X can do the job, then any employer should be free to consider hiring him. It should be up to the police to render Person X unable to do the job (i.e. put him in jail or kick him out of the country) if he's illegal.
Second, I think the prime incentive for immigrating illegally is the promise of free goods and services provided on the American taxpayers dime. This can be anything from free medical care to foodstamps to clean streets to 1st world education for the kids. Eliminate that and it becomes a lot less appealing to jumpt he border.
Sure, a few folks might still come to here to work and earn a paycheck. But I don't have any problem with immigrants coming here to earn a paycheck. I'd prefer they do it through legal channels, and to that end we ought to make sure that there are legal channels and that they work. But all on its own, I don't care if any of my self-supporting neighbors are illegal immigrants, legal immigrants, or natives.
It's true that there are more barriers to hiring legal Americans than hiring illegals. That's a real problem. But the root of that problem is that the American government has imposed barriers on American businesses seeking to hire American workers, barriers that don't apply to immigrants willing to work outside the law. Is that the immigrants' fault or ours?
