"Fair Trade" is nothing more than the Government keeping Taxes and Regulation low enough that Domestic producers can out-produce competitors. It has nothing whatsoever to do with an insane, Interventionist Welfare State attempting to "control" Trade via Punitive Tariffs. If your Domestic Taxes and Regulation destroy your Domestic Production base, all that Punitive Tariffs accomplish is to keep you from importing anything either.
If Domestic Industry is being starved by High Taxes and Regulation, it does no good to institutionalize their disadvantages by erecting Tariff Walls. It's the taxes and regulation, stupid. "Protect" a starving man by building walls around him, but continue to deprive him of food, and he will still starve to death behind those "protective" walls.
Protectionists should stop drooling in their shoes, "Tariffs good... tariffs good...." and work for lower Domestic Taxes -- not higher Trade Taxes, of all the stupid, anti-capitalist, and (quite literally) counter-productive ideas.
