This is an absurd straw man. Not only have I talked to immigrants, I grew up in an immigrant neighborhood. One of my tasks this week was to write a recommendation letter for a "DREAMER" that was deported to Mexico two years ago at the age of 18, to a country that she has never lived in that speaks a language she doesn't speak. I also grew up in a single parent household that made
way below poverty wages. I now have my PhD. "some of my immigrant peers went on to be a success" is not the same as saying "my immigrant peers were provided great opportunities to succeed". If you grow up in a wealthy suburb in the United States 80% of your class will go to college. If you grow up in a wealthy community, nearly 40% of your class will go to an
elite university. If you grow up in a poor community, less than 40% will even attend a 2 year community college. [1]
Just because I am a success, or an immigrant is a success, doesn't mean we have created an optimal system. I'm not ignoring the achievements of anyone, I'm plainly stating "just because some people manage to survive a poorly constructed system of hierarchies and go on to be successful, doesn't mean we can't do wildly better than we are.". The US favoring anyone who has money is a plain fact, clear as day. Just because someone is successful in spite of that doesn't mean it's not true.
For every person that survived the odds with hard work and some luck, there are 5 brilliant people here who don't get that chance. People who are relegated to the lower class because the system didn't give them the opportunity to succeed, and all our lives are worse for it. These people go on to commit crimes to alleviate their socioeconomic problems, or at best generally less productive than they could be. A society should be measured by the opportunities it provides for people to remove themselves from poverty. The United States does a quantifiably miserable job at this, both through education and social welfare.
It's simple enough to look at the statistics for upward class mobility and to see that the United States is worse than ever in these regards. And we are the wealthiest country in the world. Something is wrong, and a large part of the problem is the financial, educational, and social incentives provided to the wealthy and the cyclical nature of poverty.
