Biden, and other Democrats, like to talk about “good union jobs.” Unsurprising–what is a little surprising is how many conservative commentators have picked up on the same phraseology: for example, when talking about the impact of Biden’s pipeline shutdown, I’ve hear them talking about “union jobs lost” rather than just about “jobs lost.”
I’m not opposed to unions (private-sector unions, that is), they can serve a useful purpose. But they do add a certain rigidity to business operations and to compensation and promotion decisions. They are not for everyone, and there are a lot of people who have excellent jobs that have nothing to do with unions.
Democrats like to talk about unions, I think, partly for reasons of nostalgia but primarily due to the inherently collectivist worldview of the Dems: they would rather think in terms of categories of people than of actual individuals. The old feudal idea of “no man without a master” resonates with them, I think, although they would phrase it differently. And, of course, they view unions as excellent sources of campaign funding.
Conservatives/republicans mindlessly echoing this phraseology and implicitly the worldview that underlies it.
