A union is, in an economic sense, a cartel. Their job is to restrict supply of labour so that the price they can demand for it increases, making their members more money. This is why it takes over a year to join the plumbers or electricians union in many states and why it takes over 10 years to join the longshoremens union.

I am against all cartels as a matter of principle, be they the ILWU or OPEC.

OK. I'm against corporations as matter of principle. A corporation is also a cartel.

A corporation is a legal entity that provides some liability protection, and is not a cartel in any sense. Several corporation can collude to form a cartel, but a corporation in and of itself does not in any way meet the definition.
