Have you ever tried to explain to skeptics of socialism that profit itself is a type of tax? It seems like some people in the US might be more receptive if they realized they are being 'taxed' well above the cost of production of the things they buy. It might be easier for them to visualize it in terms of a tax, which they hate.
This is an excellent idea. Profit is indeed like a tax only levied by a private entity, not the government. Like a tax it represents a portion of the value produced by a person's labor that is not received by the producer (neither individually nor as a member of the collective of producers) but instead delivered to someone else, a non-producer. Then too, where tax is extracted under threat of legal force, profit is extracted under threat of unemployment where employer has not responsibility for social consequences of firing workers who do not deliver what employer deems to be adequate profit. I will work on this. Thanks for the idea!
