Recently I was explaining to a friend why I generally refrain from using the word "Capitalism":

My reasoning is mostly tactical. The word was first coined by Marx and continues to be used as a pejorative by the left. 'Capitalism' as a term implies to me that capital is special and that the owners of capital, the capitalists, are therefore the special beneficiaries of the system. This of course was Marx's view. Even today, to many people capitalist = fat cat. But the fact is that 'capital' as a factor of production plays no more of a special role in a market economy than any other factor. You and I would argue that the real beneficiaries of the system are consumers and laborers. It would in my book be more accurate to say "laborism" than "capitalism".
