Better yet, tell me why I should take it seriously in the first place. I looked over that piece a bit, as well as a number of other writings that he had there. What I saw was a whole lot of inanity. In particular, a heaping helping of one of the most prevalent features of right-wing propaganda seems to be the standard for his writings - cherry-picking something minor, overemphasizing it like crazy, and conveniently ignoring the other 99% of the picture to generate an incredibly skewed picture and conclusion. In the real world, after all, most issues are rather complex and it's usually not hard to find something that can be twisted into some preferred narrative.
To be clear, Democrats in general aren't even remotely all angelic or wise sages with perfect understanding, just like all groups of humans tend not to be angelic or perfectly wise. Indeed, they tend to be quite fallible in a number of ways. Hence one of the reasons why I quite desire for good and responsible competition with Republicans that actually are principled and working for the good of the country, rather than of their self and party alone. Sadly, that breed of Republicans sure looks like they're becoming increasingly rare, especially in the age of Fox News and the various other deceitful GOP-propaganda outlets, from "Christian" leaders preaching GOP propaganda from the pulpit - propaganda that even frequently directly contradicts Jesus' teachings - to those funded by industries like Big Coal, Big Oil, Big Pharma, the gun makers, the big banks, and so on to pump out false and misleading information to muddy the waters, trick those that it has been tailored to trick (who then may well add to it), and give pretexts for corrupt or unwise politicians - just about all Republicans these days after the extensive efforts to corrupt the Republican party by a relatively few very rich and powerful people (and without any serious party pushback against said efforts because those people did it smartly) and a far too large chunk of Democrats, going by the evidence - to give big money interests more and more and more power. Unions can, in fact, be part of this and there honestly should be vigilance against that, but it's also well worth remembering that unions were largely created as backlash to and to restrain various much larger big money interests after those big money interests went waaaaaay too far in their efforts to effectively turn people into slaves and then brought the economy to its knees with their excesses - totally screwing over massive numbers of normal people and mildly inconveniencing the very rich people who caused the problem. Those big money interests have long been working to badmouth and undermine unions in general exactly because those unions are there to prevent them from doing the exact same thing again.
