I truly believe that free basic necessities for all is the way to save the planet and ourselves. Universal basic income is just a band-aid but to really embrace freedom, creativity and development we need to find another way than hardcore capitalism.

This problem will only grow with increasing capitalism and climate change. The only way to turn it around is to come together and push for policys and technology that lowers the costs for food and housing. The rich can get their profits elsewhere than on our basic human needs.
