If you don't like them being called capitalist, then your quarrel is with a whole heap of people (and academics).
The question, like I alluded to earlier, isn't whether they are capitalist, but a question of how much. And many, after careful study, have determined them to be capitalist.
Those determinations are based on measurable things and philosophy (somewhat).
Also: you are clearly not my original intended audience. In the referenced thread I was getting low-effort, glib comments that snowballed upvotes.
Not unlike the person who deemed me to be a republican. It's easy to look at my post history.
I'm not a republican. But glib is easy. And glib, low-effort posters were the primary intended audience. Know-it-alls.
