Perhaps one of the more stupid assertions (and there are many) spread about by those on Right, including people like Mitt Romney, is the demonstrably absurd notion that government and public policy can be improved by dealing with them using business principles. As attractive as this notion may be to those who crave and succumb to simplistic "solutions" it is an indefensible position.
The purpose of a business is to make money, not to improve a society or the lot of people. Quite the contrary. Running a business so that it harms a society and impoverishes and harms (even kills) people is often considered good business, as long as shareholders or the business's owners are enriched. The purpose of government is to provide security, goods, services, and a productive economic and natural environment to a nation's people. To assume the principles that might be good for making money with a total lack of regard for harm done might lead to good government is delusional.
Moreover, I suggest, that there is very little business can teach government. Indeed, when business principles are applied to public sector services too often poor service and corruption follow. Example include profit-motivated business principles being applied to eduction, health care, and prisons.
While there may be some routine management practices used by business that might be useful in administering government programs, applying business principles in general to government administration and public policy is bad government and harms people while, all too often, enriching those who pitch business snake oil.
