Earlier quoted context omitted.
I stopped buying avocados for this reason. Its the only way to win.
Why? You are punishing the avocado growers more than the cartels. Corruption is rife. Every single transaction you make in an economy contains a percentage of evil (example: surely you disagree with some of what your government does): how did you decide that avocados are beyond your limit and carrots are not?
With the price of avocados pushing higher and higher, I think there is too much money in avocado the avocado trade. Farming is basically limited to specific areas. Lowering demand (how ever small) is making a measurable change that I fell like I am contributing to. Voting with my dollars is the only true ways to make a change. As much as this might "hurt" the farmers, it is also hurting the cartel.
