It's not even about taking jobs from Americans. It's about exploiting a group of people that have no rights. Give them crappy pay, for a crappy job where they will work crappy hours because you know they're illegal? That's the wrong answer. If it bolsters the economy so much the reform should come in how we allow immigration. However, if you're here illegally you have no rights and people will exploit that and that's how we ended up where we are.
