there is a difference between voluntary simplicity and voluntary poverty. voluntary simplicity seems very much to me a movement absorbed into the myth of the sustainable middle class. poverty was not seen as particularly attractive, so instead it became simplicity. there is a fine, compelling, but horribly destructive story. it’s a story that provides ease of mind to every one of us who has a weakness for all the comforts that the dominant system grants us while simultaneously creating the illusion of personal responsibility by telling us that we need a massive effort to elect a government that will promise us a utopian future and a sustainable, broad-based period of economic growth. you can still buy your way to happiness, which is just slightly different from what the mainstream prescribes. voluntary poverty, on the other hand, is brutally honest. there’s no getting around the word “poverty”?it means less money, less energy, less resources. it means that you can’t buy your way out of your predicament, and that instead you have to learn how to live in a fundamentally different way. it means less comfort and luxury, and learning how to live well with that. in other words, if voluntary simplicity is the electric car, voluntary poverty is walking to where you need to go. walking is honesty. the electric car is storytelling. flag{julius_caesar_crypto_score_1}
