Certain companies, such as utility providers [gas, electric, water etc] should not be profit motivated. Neither should the health service.
Do you mean the companies which deliver the gas, water and electricity to other companies and private homes? Do you think that electricity generating companies should be profit motivated? Do you think that gas exploration companies should be profit motivated? Profit motivation brings us many benefits in many industries and services, but it cannot fit all industries and services.
