OK....I don't want to come across as uneducated and I don't have a lot of time for research, so can anyone just list some pros and cons of a temporary/guest worker program?

There are stories everyday of Americans unemployed due to illegals taking the jobs for lower wages, so that con is obvious. I don't know if there are any real pros for it....although economists can probably come up with some.

How do we know what WOULD happen if all the illegals were deported....any other instances in history to compare this to? Ihear people predict what would happen, and many of the predictions conflict with each other.

Help please!
