The other is that it's much easier to get out of the lower quintile in America than those same countries.
There's a couple reasons that might be. One is that social mobility is actually higher in America, but there's a ceiling over which it's hard to overcome unless you're born there. Whether that ceiling is immediately under the top quintile or somewhere lower is an interesting question.
Edit: as pointed out, I actually misread the first graph, which is probability of remaining in lowest quintile. So, yeah, data looks like all bad news to me (unless you count those people knowing fairly accurately how fucked they are as a good thing).
That's not what the first graph shows. What you say is true for "perceived" mobility, not for effective mobility. 33% of Americans stay in bottom quintile, much more than other countries.
70 years ago college was only for the elite. Today close to half of young adults go to college. Yet that didn't fix anything.
Just below is my response to someone else, and the point there is just as relevant as here: https://news.ycombinator.com/item?id=29537081
If the children of an astronomer really do turn out to be the best astronomers, then a meritocracy should theoretically allow them to become the best astronomers in the next generation.
But they do not get to be the astronomers JUST because they had a parent who was good at that. Every generation gets a reset; if genetics really do predict merit, then sure, the arrangement will look a bit like ancestry.
It's not how hard one works, it's how smart one works.
The second aspect is what does one do with the income one has, which has a crucial impact on the person's future.
It's about the support networks that kick in when you screw up or when bad luck befalls you. Lots of middle class kids (like mine) get multiple chances to try and fail. Their parents' wealth and social connections gets to work and cushions their landing, and like Silicon Valley folk, they get to try again.
The children of working class families do not have anything close to this level of support when things go wrong. They make a mistake, or just suffer some bad luck, and they are completely screwed. Yes, everyone can get up and try again, but the difficulty of doing this from zero with no support is routinely underestimated by people (like me and my kids) who've never had to do it.
Most immigrants in the US do not "stream over the border", more are arriving from Asian countries than Latin American countries. Those that arrive by air from another country typically have more than "nothing" on arrival.
"With the granting of work authorization and the imminent threat of deportation removed, DACA recipients have experienced pronounced upward mobility in their socioeconomic status."

But TFA was about socioeonomic mobility within the USA, not comparisons with Mexico, Peru or Bolivia. The success of a specific subgroup [0] of undocumented immigrants at moving upwards doesn't refute the general mobility findings cited in TFA, nor does it prove or disprove that their success is about smart work vs hard work vs adversity support. And I didn't mean to imply that neither hard nor smart work play a role in any upward social mobility, but rather that many people forget the role played by adversity support (and it's not a small role).
[0] According the article you cite, DACA covers 832,881 people, which is about 11% of the total undocumented immigrant population in the US at present (and if tales about an uncontrolled wave were correct, even less).
It said that upward mobility is significantly lower in the USA than many other western industrial democracies, and also significantly lower than most Americans think it is.
Investing in yourself is how you become better than average.
I'm saddened by the persistent negativity I see here. Buck up, dude!
Maybe paying for college is an exception to the rule -- only because of all the grants, scholarships, loans, and income-based tuition.
With a single signature you can enter into debt and ruin your life, or enter into a bad marriage and do the same. Taking the right life decisions is essential.
I mean, it _is_ exceptional. Americans, per the article, are exceptionally overly optimistic about social mobility.
