A resurgent economic rationale for rapacious government intervention in the delivery of consumer goods and services is the unfounded claim that government can provide said goods and services at a lower price to consumers. This is because government does not have a profit motive; there is no mark-up. To some, this convenient argument may initially make sense. In the real and lucid world, it is senseless.
For example, let's assume that a product costs $100 to produce. Cheerleaders for big government would want you to believe that if the government produced that product you would be able to buy it at the same $100 cost. However, if a private business made the product, the cost would still be $100 but you would need to pay, say $120, with the extra $20 representing the businesses' profit margin. If this were only true, then government should produce everything and sell at cost. Social utopia. Rejoice Karl Marx!
The hallucinogenic logic craters when one considers the reality of a competitive marketplace where demand/supply dynamics give rise to price elasticity. Price elasticity dictates the limit to which the price of a product can be elevated and still be acceptable to consumers. The freer, or more competitive the market, the more forceful are the constraints of price elasticity. In pure monopolies, where there is no competition, a seller can charge exorbitant prices because the consumer has little alternatives. Monopolies must be regulated because they bypass the demand/supply characteristics found only in a dynamic free market.
Given the price constraints imposed by demand/supply forces, it is imperative for a private sector business to become effective and efficient in order to lower its cost structure, sell the product, and still make a profit. Hence, price levels are tight (inelastic), creating a ceiling. The cost needs to be safely below the price ceiling if a merchant intends to render a profit.
The key here is cost. Government, not having shareholders that demand profits, allows inefficiencies and waste that consequently drive up the cost of any good or service it produces. Government cannot, simply due to its political nature, produce at costs lower than what economic driven private business can achieve. If made to compete with private business, the government will kill business profit by excessive regulation. Businesses then fail. Farewell private sector employment.
In more extreme cases, government will legislate that it is the only "permitted player" with respect to a good or service and therefore nationalizes the product/service altogether. The government creates a monopoly that it gets to regulate. Foreign competitors? These get thwarted by raised tariffs that jack up their cost structure.
The government payroll swells and the cost of our hypothetical product soars from $100 to $225 and we consumers can only be comforted by knowing that although we are now paying exceedingly more, big bad greedy private business is not making a profit.
But, hey, Mr. Obama would look at that $225 cost and proudly defend it by saying: "It could have been worse, it could have been $375. Be thankful that I limited it to $225. Now let's increase unemployment benefits for those who used to work for now defunct companies that produced the same product at $100."
