People buy the shit because corporations make it and, at best, tell us we want it, and at worst, design our entire infratstructure and society around it so that we more or less have to buy it.
Nobody was asking for cars, or at least very few were, until companies started pushing them on people. Same goes for the vast majority of shit we own.
People need to get it through their thick skulls that we cannot dig ourselves out of this hole without hurting ourselves in the short term. It's decades too fucking late for that. Fixing this will cause unavoidable suffering; not accepting that is going to cause exponentially more suffering. Suffering that has already begun. We as a global society had every opportunity to avoid it, but we chose not to. There is no painless solution anymore. We can all suffer now and mostly make it through to the other side, or we can try to cling to our cushy lives of excess and convenience while the vast majority of us die. Pick one; those are the only choices.
