In the Republican debate tonight, Rubio was quoted saying, "Welders make more money than philosophers. We need more welders than philosophers."
Actually, Socrates was stone mason by trade. Machiavelli was a public administrator. Locke was a physician and also worked in government. So, being a philosopher and having a trade or profession can be quite compatible.
Maybe he should have said that we need more philosophers who are welders by trade.
