last thoughts on immigration

My last thoughts on immigration are both positive and negative. I understand that immigrants are helping out economy is some very important ways, such as crops and other low wage jobs. Lets admit it, no one in this country, let only california would willingly work long hours with low pay, so somebody got to do it. Without them we would have a major shortage in crops, as well as just a lot of jobs that are neccessary with no one to take them. However, with all those people coming over we are dealing with the affects of over population, people are tearing down land and building up homes for people who are not even from this country or have contributed anything to it Also, people of america are being put of their own jobs in order to make for the new. So basically, every issue has it up and downs and as long as it is well managed it shouldn't start any kind of chaos.
