This is where the World Trade Organization, usually a colossal waste of space, can actually be of some good use.
Let’s take one commodity as an example: sugar. The world’s sugar-producing nations need to sit down together, each with a copy of everyone else’s lists of protectionist sugar policies. And start horse trading.
“Brazil – how about if you get rid of this subsidy, we’ll each get rid of one.”
“Mexico – if you get rid of this tariff, we’ll each get rid of one.”
Let the subsequent discussions ensue. Lather, rinse, repeat.
Working together to tear down trade impediments makes a whole lot more sense than working unilaterally to continue building them.
And someone needs to make sure the non-essentials understand this – when they are back from their back-paid vacation.
