I mean, I get that you don’t like how they talk on Lemmy about it, but the quote from the study even talks about how the surplus could be used for additional consumption and everything. Study is here
I think we all have different things we want in life and with such a big surplus there is room for most of us to regularly enjoy that. I do not believe that they argue that we will NEVER be able to enjoy different food. That is as you have mentioned not functional or good for people to work together and live together. Disregarding the many people with different cultures that have moved somewhere else.
I think the study more clearly argues that we can afford to take care of everyone on the world if we wanted to. That there is a viable way and that that way is not as you are implying necessarily a deprived space with tight margins. Because living is about more than slaving away like a 12th century peasant to accumulate more wealth for a king somewhere far off.
I agree, I think in the context of the comic with „stoic and strong“ it does feel weird to say that they do not make you weak, because he is obviously struggling.
Like you I think the point should be more about generally building up to better deal with all our emotions - even unwanted ones - and be more comfortable while experiencing them.
But I also see how in the comic it‘s easier to say to a buddy that he is not weak to comfort him to open up and then later on circle back to his ideas of strength and stoicism. But I think we have to rethink standards and ideas about masculinity and emotions for sure.
