Putting aside what's right/wro

For many, being a “wetbacks and lazy locals” takes a lot of courage. They might take advantage of others most time, but it won’t change the fact that they are at the bottom of the society. Because things couldn’t get worse for them, nothing can really hurt them. Ironically, they can take liberty of their social status. I am sure many of us, as you said, working hard and paying tax, live a middle class life, or work toward a middle class life. Putting aside what’s right/wrong, that is the very reason we should avoid certain behavior – they will come back and hurt you someday.
