That last panel hit me like a truck because... yeah, that's what people think happens when they do their little personal choice things to pretend they matter.
Like, they really buy like a paper book once and go "ah, yes, Bezos is fuming right now" while he makes another billion.
We have lost all sense of how to influence society and all ability to gauge scale. For all the folksy traditionalism in this (which includes driving a gas guzzler from the 70s, apparently?) the Internet has created this entirely disproportionate sense of our footprint on the world and this strip is as much a result of the hyperconnected dystopia as everything it's complaining about.
In my experience this is extra bad for Americans who, frankly, didn't need that much of a push to go from their individualist, self-centred perception of society to this vision of sitting on a couch listening to a walkman as activism.
