Perry:
The capitalist must perform to market standards. Competition will put him out of business if he provides an inferior product or service. He is furthermore constrained by his customers, stockholders, board of directors, lending institutions, as well as numerous laws, and, if all else fails, product liability statutes.
What competition is there between monopolies? They can afford to give shoddy services to their customers because there is nowhere for them to go to that doesn't treat them the same.
And what about constrainment by their workers to alleviate themselves from exploitation?
Yes, I know. You despise the workers considering them sub-human.
As for product liability statutes would you find it OK for them to sell poison as food? Like China did when several infants died from contaminated infant formulas (Never buy any food from China!)?
