Something that I think forms an important foundation stone for how I see things, especially in the wake of the recent trade unionism dust-up — prices for labor are still prices.
Wages, just like the prices for corn or pencils or shoes, are not determined based on how we feel about the person getting paid. They are an information-bearing signal based on supply and demand and the ability of the seller to satisfy the desires of the buyer. They are not a function of philosophy or morals or warm and fuzzy feelings. (Or cold and bitter feelings.)
This also applies when the conversation shifts to farm subsidies (*ahem* Mr Vilsack!), or trade barriers, or the minimum wage. Liking teachers or farmers or waiters or poets is not a reason to adjust the prices of their output.
