You know, it amazes me that people never see conflicts of interest internal to government itself. The USDA guidelines are a prime example.
Think about it. The guidelines purport to be an objective assessment of what food we should all buy and consume, but what is the USDA primary mandate? Oh, yeah, to advance the interests of agricultural producers in the US. It’s the Department of Agriculture, not the Department of People Who Eat.
Like all “regulatory” agencies USDA has long ago succumbed to regulatory capture, and now exists largely as just a means for people who make their livings in agriculture to advance their economic interests using the power of the state. The USDA only has an institutional incentive to advance the welfare of food producers. The USDA has no institutional incentive to look out for the welfare of food consumers.
By sheer coincidence, the USDA recommendations for the percentage of a particular type of food we should eat always seems to roughly parallel the relative economic size of the agricultural sector that produces that food. I wonder why?
One of the biggest reforms we could make in government would be to legally separate promotional, regulatory and research powers.
