How would you justify it's you should get the work/money, not imigrant worker? The fact your parents immigrated earlier than they should justify it in your opinion?
The fact that I'm American justifies it. If Americans flooded into say, Somalia, bought up all the houses, took up all the jobs etc, you'd be horrifically offended.
Americans have no where else to go. This is my home and I will not abandon it. You can't just drop 50 million extra workers into a country and expect people to just take it.
