Interesting matrix about free trade and protectionism. The matrix found here draws inspiration from Cato's "Free Trade Free Markets" report mentioned here.
There is an explanation too:
"Free traders are those that oppose both barriers and subsidies. Interventionists are those that support both barriers and subsidies. Isolationists are those that support barriers but oppose subsidies. Internationalists are those that oppose barriers but support subsidies."
Where do you stand?
