Well first of all, it doesn't piss me off because that isn't true. They don't just show up and "do as they please". The only thing that pisses me off about illegals is the fact that some of them *some how* get public aid, welfare, and other chunks of our tax money. I'm pissed at the agencies that dole that out, what they hell kind of check are they doing?
We don't have people from all over coming in, we have people who can afford it coming in. The USA used to be the land of opportunity, but that's not the case anymore. In order to get in here, you need to have things going for you already. You need to be educated, have a job, and have a fair bit of disposable income (5 figures) set aside for filing fees and other BS. Nevermind the expense of having to visit your embassy for almost every step of the proccess, which is a cross-country trip for many. If it was that way when your ancestors came here, they'd probably have never been alowed off the boat.
Kick'm allout, and give them a legal avenue to come in that doesn't involve 3 years worth of their annual income. Hey that sounds like a workers visa.
