Well, the bestestest argument of all time. If you don't like Mexican immigrants, why don't you go to canada? If you like capitalism so much, why don't you go to China (do the research, China is ultracapitalist)? If you like no socialized health care, why don't you go to Singapur? If you do like overacting leaders so much, why don't you go to Hungary with Victor Orban?
Many people leave their country when they are dissatisfied with their own, look what’s happening at the souther border or all the Muslim immigrant going to Europe.
