The bottom-barrel students never end up in American colleges, after all.
The chief difference is cultural - in Asia intellectualism is celebrated and demanded. Parents don't push their kids to football, they push them to academic achievement. Not being able to make it into college isn't worn as a badge of honor, it's downright shameful. I have personally known people who've shipped their kids away from home to some backwater third-rate academy, just so they can hide the fact that the kid couldn't get into any school locally.
Beyond parental pressure, peer pressure also largely pushes people to academic achievement. Having high marks won't get you beat up - in fact it commands respect (within reason). Having poor marks likewise isn't cool like it is here, but is similarly embarrassing.
Keep in mind though, that this has some consequences that academics who opine about the lack of American work ethic consistently fail to mention:
- Appreciation and participation in the arts, both as a college study, and as extracurriculars, is ridiculously low. People who study the humanities are looked down upon, I even know one guy who got disowned for it.
- Social integration takes a backseat, often to disastrous results later. In Taiwan is it not irregular for a middle school child (age 12 or so) to be at some form of school for 14 hours a day. There's literally only spare time to eat and sleep (and sometimes not even). Socialization is minimal, and add this onto the culture of living with your parents well into your 20s, it produces some seriously socially inept people.
Japan is already dealing with these consequences - look up "hikkikomori" if you're interested.
It take a certain to 'laziness' to solve a problem elegantly rather than through grinding effort.
This kind of laziness, the kind of laziness that great programmers laud, can require a bit of effort. It's the kind of effort mathematicians go through when they look at problem for five minutes before saying "it's trivial".
The America that built Silicone Valley sometimes had this right balance between effort and "laziness". Present America certainly seems to have taken a wrong turn.
If anything, its an appreciation for elegance.
But maybe its just laziness as you say. If a solution looks like a grind, I will spend just as much time trying to find an elegant solution (probably more) because I don't want to just grind out the solution.
The introduction of AP and other advanced classes was a godsend for intelligent kids being able to be reaffirmed by their peers. But a lot of kids don't really want to be in school, and like to pick on kids who do. (Which was my experience as one of the "smart kids" at a private school in Charleston, South Carolina.)
Yes on the social integration, though. People don't really have the time for much socializing until college.
And you never know why a student chooses a college until you ask. They might be offering something in their major. They may know an alumni who can get them a spot (with the proper grades of course), or they might offer more scholarship money. If you're family income is $200 a month are you really going to turn down a free education?
Or at least, we have no reason to think that "business students are lazier than other students" tracks or causes the difference between Americans and others that the author focuses on.
From personal experience i've found the hardest working students to be those needing to get into professional school (law or medicine) as well as low-income/disadvantaged students who couldn't afford the $50k tuition/year to attend a private college.
Consequently, you could end up with a student body of pretty highly qualified foreign students but American students that didn't make the cut at more desirable colleges in the US. (Again, there are plenty of reasons why great students choose colleges that are not high on the prestige list, but this effect doesn't need to be large to be real.)
For some reason I have met a number of Japanese students that spent 4 years at schools I had never heard of (like X+State+University+Branch Campus in a tiny town). And they usually were very good students who went on to good grad programs, employment, etc.
The point being that the quality/reputation of the school will not be proportional in the same way to the quality of the domestic students versus the quality of foreign students.
A final anecdote, when I was at a university in Germany, I saw a cheesy poster advertising a scholarship to study in the UK, sort of "Apply Now! Come to England!". The scholarship: The Rhodes. I asked a few Germans and none of them had heard of the Rhodes Scholarship, which is probably the most prestigious scholarship in the English speaking world.
