Hard disagree: The above advice is relevant to everyone, even if you're not struggling to survive. We are all victims of capitalism, and even those of us who are living relatively comfortably under this system need to recognize that the billionaire class are the enemy of all life on Earth. It's not a good system for you just because you get the best table scraps.
If you stop caring about those who are barely scraping by just because you're not then you're a fucking idiot.
