Vegan? Awesome. but humanly ethical?

Interestingly enough, I have a good friend who is into fair trade and at least with coffee, they found that fair trade farmers get less because the government takes more through taxes or other means, they now buy coffee from someone else that does not participate in fair trade but rather charges fair trade prices and with the difference goes to their growers and gives them. Bonus directly or buy the village she's, uniforms etc. So I guess the point is its not good enough to just check the fair trade label, if you wanna do the best for these people see how much money is literally getting into their hands.
