Just read this article.
Capitalism has been exalted as the ultimate form of perfection for the human race. We should all embrace capitalism if we want to become rich and powerful. That's true...capitalism does make people rich and powerful, but that's only for a handful of people. Capitalism, overall, deprives the majority of people of power and wealth. Capitalism is founded upon inequality and is no different from feudalism or slave society. Except now you have machines powered by oil and natural gas to grow the economy instead of human and animal power in the case with feudalism and slave society. Either way, capitalism is based on inequality, and is no different in that respect from feudalism or slave society.
We need a system that embraces equality and maintains balance with the Earth. Capitalism also needs to be abandoned because capitalism is a part of the infinite growth paradigm, which demands infinite growth in consumption and population. This is just not possible on a finite planet.
We need to abandon capitalism and the infinite growth paradigm. We are doomed as a species if we don't abandon capitalism and the infinite growth paradigm.
