I love Dilbert and never saw it as overtly political although sometimes Scott Adams can be. But apparently you cannot joke about ESG without consequences.
I liked Dilbert a long time ago (90s-early 00s, where I saw it as kind of a window into adult work life as a teenager).
That's not impossible of course, but it's not like I was uninvolved in those topics.
Either way it's still not an second language thing. It's a using acronyms without definition thing.
But anyone who reads company annual reports (eg. for personal investing), or the financial bits of a newspaper (online or otherwise), or even reads their annual superannuation statement, would very likely have seen the term used (in OZ).
I haven't really seen it crop up in the online stuff I read (some of it Australian financial), but I can see how it would be easy to miss as well.
Another, maybe more infamous example is the Sharia-complaint stock grouping, which bans alcohol, tobacco, military industry, pork, and the sex industry.
Yes I have some investment in the latter indices.
