That doesn't make much sense if the US is a hell-hole of capitalism grinding people into poverty (as immigrants usually have little).
In 2016, 1.49 million immigrants came to the US. The median age is 44, so they're hardly all children.
Meanwhile, an awful lot more want to come but can't get in legally.
> This is the most ridiculous proof that America is the land of opportunity I can imagine.
People run to opportunity, not away from it. https://www.migrationpolicy.org/article/frequently-requested...
A lot of the planet is just terrible. Of the places that aren't terrible many wont let you just sneak in and make a living if you live a cash and carry lifestyle.
At best you can prove that the US is viewed as better than their current abode by people that don't live here.
This is the definition of damning with faint praise.
For example, you can get an MIT education for free on youtube, you can open a business on github for free, you can get funding for free from kickstarter, you can advertise for free on reddit, you can reach a worldwide market for free via the internet, you can write and sell a book on Amazon for free, and on and on. Nobody needs to know your age, gender, ethnicity, religion, location, disability, marital status, etc.
There's never been such opportunity, right here anywhere in America.
"But we also have lots of studies showing that the best of the lowest socioeconomic class almost never do better than the laziest of the uppermost socioeconomic class."
The entire point is that there is inequality of opportunity and unequal return on equal potential not that there isn't opportunity.
If you recall the post I replied to you said
"So why do penniless immigrants keep coming here? Do they know something poor people in America don't, or are they simply misinformed?"
This is terrible logic. This is a wealthy nation with lots to offer but people here have actual problems here too. You are glibly dismissing these actual problems with bad logic which personally makes me very angry. Who the heck are you.
Imagine if someone was talking about how racism was still a problem in America and you piped in with how your black doctor friend's practice was doing great and people shouldn't let negatives become a self fulfilling prophesy.
Well no shit but what we were actually talking about was inequality in America which we can actually do something about.
From the individual's prospective whatever society does the individual ought to do the best they can and for many decent lives await in spite of challenges. From the perspective of society we ought to try to maximize everyone's chances as best we can.
