Way to stereotype
No you aren't going to see Mercedes Benzs in the parking lot, but that doesn't mean everyone who shops there has "below average intelligence and technical inclination."
The whole Wal-Mart people are stupid argument reminds me one of those generic All Americans Are Stupid blog posts that have become all the rage on the internet over the last few years.
One in particular I remember reading was some guy stating that 78% of Americans score less than 90 on standardized IQ tests. I'll gotta give the author props for writing a well worded post, but he fails because he misses the whole point of IQ tests.
Firstly, on average, the entire US populations cores 20 points higher on IQ tests now than they did in 1900. Does that mean everyone in the 19th century was technically mentally retarded? Considering people drank mercury like it was going out of style back then, there might actually be a point to that, but...
IQ tests are
standarized, meaning that they're graded on a curve. In other words, if everyone in the country is scoring 120, then 120 becomes the new 100, which is supposed to represent the average intelligence level. So if everyone only scores 90 at max, then either there's been a recent epidemic of mild brain damage, or no one would be scoring 90 in the first place. They'd be scoring 100, since that's the median.
Then it went into some BS political issues, and how people who believe X are generally more intelligent and blah blah blah. The whole thing was just an exercise in mental masturbation, written so dude guy could tell the world how much smarter he was than everyone else because he thinks such and such and so on and so on.
Kinda like people who think of Apple stuff as a status symbol, and think they're smarter because they go to the local trendy organic place instead of Wal-Mart. Comeon, people. They're phones and stores. They don't say jack about crap besides I shop here and call people using this product.
