Well we have to start somewhere. These people are already being exploited and in horrible positions. We do a lot of foreign aid work in these countries as it is, but a lot of time the money just gets passed around to corrupt officials. If people want to come to the US and work, then the money goes to them directly and they will often send money back to their families and it does more good that way. Plus, if they come here legally to work, then they would be able to earn minimum wage, maybe limited benefits.
