Here is a good good followup article on how Costco treats their employees.
Opening paragraphs:
Abraham Lincoln, the first and greatest Republican president, and the man who held this nation together during its bloodiest and darkest hours, would not be tough enough to survive in 2005 on Wall Street.
It was Lincoln who said: "Labor is prior to, and independent of, capital. Capital is the fruit of labor and could not exist if labor had not first existed. Labor is the superior of capital and deserves much the higher consideration."
This sounds appealing, but it contains an exaggeration. Capital does have an existence somewhat independent of labor, inasmuch as it is rooted in the physical goods of the world that God created. It's not surprising that Lincoln, with his somewhat messianic Scriptural rhetoric, would have a tendency to devalue the material world.
