Fair trade means that those lucky few who get themselves involved in a cartel can sell their products for a marginally higher price which, at least in theory, gives them dignity. What it means in reality is that a majority of food growers now must compete not only with CAP and US assisted first world producers but also cartel members.
And those in the cartel get only marginally more than they ought to (because the system is clunky) while their goods cost a lot, lot more.
Well, it's also worth pointing out—for those who do not read Private Eye—that the people who really make the massive amounts of cash are the retailers and the Fair Trade company itself.
It is, like many socialist ideas, good in intention but cruel and counterproductive in practice.
This is because most socialists are fuckwits for whom the phrases "unintended consequences" and "economics" might as well not exist.
The only truly fair trade is free trade, ceterum censeo Unionem Europaeam esse delendam.
