Second, I thought it was appropriate to look at the immigration debate through the lens of its winners and losers, rather than immigrants and natives. In past years, it has been unskilled native workers whose employment was threatened by immigrants. However, it should be noted that as immigrants education level rises, doctors and computer scientists may be as threatened by immigrants as farmers and factory workers. That said, it is still the majority demographic (white men, in the USA) that will feel their nation's identity threatened by immigrants, and it is precisely those people who elected a nationalist president who will fight to salvage their vision of the USA.
Obviously, the ultimate question regarding immigration is how inclusive we should be with our borders. Still, even as an American citizen, I feel uncomfortable answering that question - who am I to say whether or not a Mexican family is deserving of American citizenship? That said, it must be answered in order to ensure our country's security. As to whose duty it is to answer it, I don't know.
