Meme words attract other meme words. On average people's brains tend to operate on simple reductive trends, things get grouped with over simplified patterns. You can fight it but they'll just express the same ideas in double speak if you make it a no no phrase. I wouldn't use it personally but like what OP is saying, it used to he "neoliberal" then that became boring/overused so they invented "late stage capitalism" as the new bucket to throw every criticism of modern economics into. Likewise with "cultural Marxism" for popular social justice trends.

There will be a new phrase for these same groupings that we'll all get upset about in a few years once these get fully played and become taboo.
