Immigration reform

I work for a landscaping company. The work is mainly seasonal, so we hire mainly seasonal workers. The starting pay is pretty low, the work is pretty hard, and the hours are pretty long. The prospects of hiring goods people? Pretty slim.
To combat this, my company takes part in a government program that allows Mexican workers to come to the US for 8 months and work legally until the season is over, after which they return to their families until the following year. I once had to spend a week in another city, away from my wife and sons, for work. It was the longest week of my life. These men are willing to do this for 8 months at a time to help provide for their families. This to me is admirable.
They come here legally. Most of them have been doing it for many years and are an important part of the culture of the company. It is,without a doubt, one of the few successful government programs I have ever heard of. Maybe that's why the government is putting an end to it. We had to tell our employees that they wouldn't be coming back to work for us any longer after this year, not because they are doing a bad job, quite the contrary. They are our best, most experienced and knowledgable workers. They are not coming back because, in this economic climate, the government feels it would be better to give these jobs to American workers.
In a sense, I can see the logic behind this. The flaw in the logic is that Americans truly don't want to do this work for this kind of money. If they did, we wouldn't have had the program in the first place.
At the beginning of this season, we hired about 20 local people because we were informed that the number of visas was being reduced. We still have 3 of those people. Do the math. We will have 15-20 positions to fill next spring. That means we will have to bring in 100-150 new employees to find 15-20 that will actually work out. Even in these economic times it will be tough to find that many people to even apply, let alone stay through what is arguably the most demanding time of the year for us. But that's not a big deal.
I feel badly for my amigos that I won't get to work with anymore, but that's not what bothers me the most about this situation either. What bothers me is that the government is punishing people who are playing by the rules, waiting in line to get a seasonal visa to work in the United States, leaving after it expires, and hoping for the oppurtunity to return the next year, while at the same time, policemen aren't allowed to question the citizenship of motorists they pull over for traffic violations. Even if the government does catch an illegal immigrant in the commision of another crime - in addition to being here illegally - nothing is done about it. Some cities don't even report them to INS. They are merely released and sent on their way. If they are deported, they come right back across and continue to live and work here illegally. Apparently that's all right. The jobs the illegal immigrants are working at don't need to be saved for American citizens, just the ones that are being taken by the legal, temporary immigrants. I guess that makes sense, right?
I guess I should have known this was the kind of immigration reform Obama was talking about. After all, seasonal workers don't vote, illegals do. And they vote Democrat in droves.
