What's wrong with Immigration?

Is immigration really that bad? Why? I'd rather give immigrants here a job if they will then spend the money here... it would help the economy more than companies sending the factory down to mexico.  At least if they live here, and buy things here, it will help the economy here, rather than the alternate... as I said.. our companies go searching elsewhere for cheaper labor.  What do you all think?

If we put more stress and penalties on compnies that employ illegal immigrants it would seriously reduce the amount wanting to come in. the reason they come in the first palce is cause they know they canwork under the counter for less than minimum wage for full time jobs and companies dont take the time to look at their background properly. more border security, yes, but you can't just fortify the front lnies, you gotta make sure the goal of these people is essentially cut off. charge heavy ass fines to companies that fail to properly background check their workers, and put that money toward border security.

i feel the plight of these people, trying to leave an unbarable situation, but that's no excuse for coming into the country illegally. i'm actually thinking a guest worker program wouldn't be sucha bad idea. but pay them what normal americans get, even if it's minimum wage.
