Money has been associated with Bad Things (shit, piss, dirt, evil, guilt, shame) basically since the concept of exchange was invented. Money actually used to be something separate from the process of exchanging useful goods. Early societies basically used "money" objects as a way to swing their dick around. If you have away a lot of money, it meant you were a Big Deal and the person who took it took all the guilt away.

This is an important lesson today because NGOs and charity - which the Left is obsessed with - is that exact same impulse.

Marcel Mauss's The Gift covers this in more detail if you want a read.
