I grew up on the fringe of a...I guess technically it would be a large town, going by Wikipedia's settlement hierarchy. The population in-town was either around 50k or 80k if you included the nearby Big State University. Now, my particular house was outside of city limits, so I grew up going to school with a lot of the folks that Wong described in the article - these were people who, by the time I was in high school, were having to get up at 4AM to go feed the cows, check the tractor, make a run around the fields to see if there's any major problems with the crops. These were not bad people, these were people who simply wanted to get up, get on with their day, and make sure their family was taken care of.
(I lucked out, because my father was one of the local doctors, so I always had the cool stuff over at our house. 'Cool stuff' being things like the latest video game system - as opposed to a secondhand model from the previous generation - a big-screen TV, multiple computers; though in the defense of my friends, they always had a bigger yard than I did.)
I had - not a significant portion, but we did have minority students at our school, I got to see them a lot because they were usually in the advanced courses along with YT - a similar experience to the writer when dealing with minorities in-town. No one was ever mean to them, denied them a job, told them they couldn't hang out for a BS reason, or whatever inaccurate illustration the elites that Wong mocks (quite rightly) come up with this week. And yet to hear the elites speak, you would think that small-town America would be a blight zone for minorities, a place to be avoided at all costs because it's still the 50s and the KKK can come and put a burning cross on your lawn.
(Side note. In the future, whenever you hear about people railing against 'traditional America,' see how many times they invoke the images of the early half of the 20th century. Multiple generations of Americans have been born and raised - and another is in the process of being raised - since those days. I did, and the results were surprising.)
In the end, to me, it comes down to empathy. Are you willing to go out of your comfort zone and see what it really is like for the people who don't live next door to you; are you willing to care about their problems; are you willing to allow people whose point of view, whose values, whose way of life is different from your own? More and more I see the ego-driven, self-centered mentality of 'I got mine, everything's OK' coming to characterize our culture.
