You don't have to try very hard to put a positive spin on the fact that everyone is making more money, women are becoming more equal with men, and previously poor non-whites are now finding more jobs. What's not to like?
Speaking as a leftist who disapproves of "honesty" and "fairness" to still-living opponents in a culture war... haha, no way! Why the flying fuck would we want a "positive spin" on a competing project, especially the fact that it seems to move towards our own declared preferences? We want people to get unhappy, restless and desperate; that's the only opportunity to really engage their implicit assumptions! Our folks have even been kind of up-front about that, really:
"I come not to bring peace, but to bring a sword" - Matt. 10:34
"...the worst slave-owners were those who were kind to their slaves, and so prevented the horror of the system being realised by those who suffered from it." - Oscar Wilde, The Soul of Man under Socialism
"The first step in community organization is community disorganization." - Saul Alinsky, Rules for Radicals
Of course, it's not very certain how much actual influence hardcore and committed leftists really have over American upper-brow media. Nonetheless, it's fun to pretend that someone like Dumbledore on crack might be behind our ever-present intellectual confusion.
(I'm just making random Aqua vs. Turquoise noises again.)
P.S. I'm so adopting "Dumbledore on crack" as a brief summary of the Frankfurt School to recommend it to HPMOR fans.
P.P.S. Although the "cultural Marxists'" reputation on the modern Voldemort flank is rather more impressive than that of Dumbledore's - certainly a plan to "destroy the Western civilization" sounds rather bold and badass. Unfortunately for the Right, as shown above, such "destruction" and "subversion" are in fact just an ancient, refined and respected tradition of the Western civilization. It suffuses much of our general cultural outlook and gives it a unique character, I'd say - or, some angry and cyncial observers ...
ETA: The table linked by Landsburg has been called into serious question by Evan Soltas [H.T. CronoDAS]. I edited the post to leave only the table to provide context for the comment discussion of its status.
Economist Steve Landsburg has a post [H.T. David Henderson] about the supposed stagnation of median wages in the United States in recent decades. In the linked table median wages have risen for:
