Government ineptness in tax policy and the effects on production while complicit doesn't excuse GM for it failing. GM's failing is a result of not just taxes punishing production that chase jobs out of America, but a chain of choices and compromises with an equally complicit union.
Unions can not vote them self's more value for work performed. Only a free market can ultimately determine wage, artificial constructs forced on a companies create inefficiencies in the market. Eventually they are corrected though the failure of those business and the success of those that adhere most closely to the natural principles of a free market.
The same applies to nations and the markets they construct. The income tax is just one of those artificial constructs that create inefficiencies, resulting in an eventual correction either though our ultimate failure or success in adopting principles of a more free market.
The Fairtax from a taxing perspective, imposes the least amount of market distortions.
No longer can lobbyist distort the market though tax favors, therefor the fairtax supports a freer market with out artificial constructs. the fairtax removes many of the inefficiencies that income, capitol gains, corporate income, and payroll tax puts on America's economy.
