We surely need it. Without Mexicans and Guatemalans we'd all starve or have to raise our own food cuz Americans plain won't do that kinda work no more.
And why is that? Americans used to do that kind of work. What has changed?
we can raise plenty of meat , potatoes and grain with us old white boys doing way most of the work
plenty of cows were milked by white folks too before the corporate dairies put family farms out of business
and its a fact the corporate dairies wouldnt exist without the messican/illegal workers
