I low key hate that comic. It makes a false equivalency.

Recognizing a car could be safer isn't contradicted by owning one. If anything, ownership should give you more insight into the material problems of the item in question.

Likewise, society is just everything. So suggesting improvements isn't contradictory.

However, there is some hypocrisy in lambasting the maker of the very luxury goods you purchase for exploiting people. You are kind of justifying the companies' exploitation by purchasing from them. And you can advocate for change from these makers without supporting them with your money.

And some people do come with the attitude of "I don't want to change a single thing about my behaviors or sacrifice a single thing, but I expect the world to get better somehow."
