There's a lot of potential, economic opportunity in Latin America.

Why should Latin Americans be encouraged to work like slaves on gigantic farms in the United States when, with the right support, they can have their own small businesses and build up their communities in their home countries?

Sustainable agriculture isn't the only economic opportunity in Latin America.  It's like anywhere else in the world; it has its unique challenges, its unique strengths, and the universality of human ingenuity and possibility.

I really disagree with the people who are comparing immigration to the United States in 2019 to immigration to the United States 100 or 200 years ago.  Not only are those people neglecting to mention the terrible conditions in which millions of immigrants had to live and work (abuse and exploitation of impoverished immigrants are the only things that HAVEN'T changed), it is those people who are being ethnocentric and, for lack of a better word, silly in their insistence that the United States is the only place where it's worth it for people to invest their lives.

The principles and practices of democracy and of regulated capitalism are known to the world.  The United States is no longer a political experiment, it is a success story which has obliterated every other country's success story for over a century, although we're not the only success story and nobody has to continue to act as if we are.  Other countries can be as successful as we are; although countries which are smaller and which have fewer resources probably can't be successful on the same scale as the United States, that won't matter as long as everyone has enough to eat, a place to live, an education, a good job, a social life and recreational pursuits.  Most people don't need more than that.
