Moridin, Yorick, for a fair amount of people, it is not that they don't want to buy free range eggs (as an example), but that they just can't ! In our 'developed' countries, companies never stop trying to pay people less and less, and if they protest, the company just closes and goes away in a country where it can cut down salaries because people there have no choice.
I myself buy free range eggs, and am willing to pay more for stuff if it is made in a greener way, but I never forget that the fact that I effectively have this choice available is a luxury. I have had the luck to be born in France, the luck to be born in a middle class family, that gave me the luck to be able to pursue studies and get a good job and a good salary, but I will never forget that a lot of people around the world don't have that luck, and are not given choices. I fervently believe that foremost we must strive to create an economical balance between all countries, so as to lessen the power of today's big monster companies. Because if we don't, peaceful and humanist and green ideas will always get f***ed.
