Dam, I didn't know the 80s started in 2001. Or is it just that that's the chart you can find with "two minutes' googling" and so that has to be good enough because that's the amount of effort it takes to find something that vaguely seems to satisfy your confirmation bias?
Okay, though, let's just look at the chart you link. Let's assume that "inflation adjusted dollars" tracks purchasing power parity perfectly over that period and look at these numbers in relative terms, because that's what actually matters for stuff like "Who is competing to buy the limited housing stock available" or other things that actually matter to people and aren't just numerical games
31k to 44k? Cool. Seems like a lot. That's a 33% increase in the median income over that period! Over the same period, the top 20% bucket on the same chart grew from about 67k to about 103k, or by about 50%. The .0001% income bucket grew from 30m to about 60m, or about 100%. Keep in mind that the marginal value of extra dollars is considerably higher the fewer dollars you're making. So over this period of time, the Gini Coefficient, which measures inequality, has drastically increased, which is what you'd expect given the argument the article is making
Now, maybe your point is that the one number, the median income, that you're talking about has gone, I dunno, vaguely up in some period of time. It seems like this misses the point of the article in favor of nitpicking about a minor factual error. "Look!", you might say, "they said median income went down when really it went up!" That seems to be your entire argument here, and it's fucking stupid, because if you're going to fixate on a minor factual nitpick, at least get your facts right. 2001 is generously a whole decade and some change out from the 80s
