Very few actions that people take are consciously intentional. What we call “consciousness” is more like a recorder than a computer. The natural computer in our brains works with our senses and trained habits to run our activities. Consumption is what it does best, and we follow that activity with work to pay for it. Then we tell ourselves a story about how we really always wanted to be a tool of the megacomplex of civilization. Consumptionism is the problem. Capitalism (more accurately; mercantilism) amplifies it. The opposite of consumption is generosity. The opposite of capitalism (negative feedback) is sales tax.
Yes, all politics are one dollar = one vote. If you want Change, keep it in your pocket. If you want systemic change, advocate for things that teach people to keep it in their pocket. Fairtax.org is a start. Double the rate and increase the prebate (minimum income to grow your own food).
People will make better choices only when they have better information at the point they choose. That is almost always at the checkout.
