I'm asking how much. We have a ring-fenced dairy sector and ring fenced apple sector in Australia, biosecurity typically defines the protectionism. We don't pay this level of excess for milk, cheese and apples.
You could give direct income support to rice farmers and not recover it by insane pricing for Japanese rice.
If memory serves, the whale meat was virtually given away but by no means cost nothing to hunt, flense and store.
Farm subsidies does seem like the well tested approach. A lot of people in the US complain about them but I quite like having the option of some ridiculously low cost staples if I'm willing to forgo quality. Placing the burden on the taxpayers as a whole seems like the right approach for things like food security.
