It's not that hard to find "a" job... The pain is finding one that is suitable to your situation (be it salary requirements, location, hours, or something else).
Besides, there's nothing stopping unemployed legals from taking the jobs back right now... They just need to be willing to work harder, better, and longer (they're so superior - this should be easy, right?). People aren't willing to do this. It is a job they don't want. The argument absolutely does wash.
if you are unemployed, and need a job, your "situation" is to find employment.
i'm a mechanic. when i've had to, i've driven tow trucks, delivered pizzas, delivered newspapers, cooked, washed dishes....whatever i had to do to keep money coming in.
where the illegals hurt us, is that even IF you wanted to take a job washing dishes until you found a job in your field, you won't get it, 'cause jose is doing it for 3 to 4 bucks an hour, paying no taxes, and getting healthcare, compliments of you and me.
there is NO reason to allow them to continue here illegally. now on the other hand, if they want to come here legally, and work legally for the going rates, then i see/have no problems with that at all. i would/do in fact welcome that.
