Philantropy or Capitalism

Heres the question. When the world needs to reduce its waste and consumption, is it a good idea to create a vehicle to promote capitalism and consumerism in order to "raise" funds for the poor. Or are the capitalists just increasing profits for themselves and creating better economies for their products?

I believe buying stuff because it supports breast cancer or aids relief is counter productive. These endeavors only donate part of the profits. They also promote consumerism which I believe is the biggest problem globally. We must live less.
