I'm no fan of social media and I'm not even a big fan of capitalism, but isn't this kind of reductive? You can always point out bad things and try and extrapolate that outward.
We live in a time with an extremely low murder rate (historically speaking), a very high literacy rate, the ability to keep in touch with family members across the world extremely cheaply, eradication or near-eradication of lots of diseases. If I were to extrapolate that outward then I could do the same kind of logic to talk about how great everything is.
I guess I just find this kind of doomerism to be extremely tempting but ultimately just reductive.
