Are there jobs americans won't do, probably, but it isn't just americans, even legalized immigrants will not do them. Although, that is probably more an issue with wages, than it is with the job. The $6 lettuce is a scare tactic, espoused by those whose interest has little to do with the common man and more to do with profits.
Interestingly enough, illegals in many cases do get above the minimum wage, but for an employer it still makes sense, since he does not pay all the other taxes, nor does he have to worry about OSHA, workmans comp, unions etc. For the employer it is a win win situation, for the rest of us, well not so much.
It is interesting to note, that even legal immigrants from south of the border is starting to view illegals with a different set of eyes. They are getting priced out of the market by illegal labor. Of course, they are stuck in the middle, since although they are upset, they do not want to press the issue against their fellow man, for fear of a backlash. (Just look what Cosby endured when he spoke about african americans and their language.)
But back to the jobs, we supposedly won't do. So let us presume this is correct, and that it has nothing to do with the wages, the jobs are simply beneath us. Okay, we need someone else to do them, but we need to control who does them, we need to ensure that those who employ them are complying with the law, be it OSHA, taxes etc. We need to ensure, that those who do these jobs are protected and are not indentured servants, otherwise, we are simply revisiting the slave issue, something most americans adamantly oppose.
Is the solution to build a wall, well, it seems silly to do so, although I am a proponent. It seems to me, that it would make a lot more sense, to force employers to make a greater effort to ensure that those they employ are here legally and to fine them heavily if they are caught employing illegals. Now, certainly, there is a lot of fraud going on, with SS cards, green cards etc, however, a little more diligence would probably go along way. The resident deckbuilder on here, is doing us all a disservice, just like those who employ illegals, he didn't even try to ascertain the legality of the issue, which would have been quite easy. Further, his veiled comment, that he was not about to pay the going rate to a carpenter should give pause.
I fully support legal immigration, I support work visa and the guest worker program, but unless we ensure enforcement of the illegals, the above programs makes little sense. As for blanket amnesty, even if it involves fines etc, to those alrady here, I say a resounding no. We should give them one chance to seek change of status, if such is denied, we should expect them to leave asap and if it means we have to arrest and deport, so be it.
Sadly, I am not holding my breath that we or the politicians have the guts to do what is required!
