Obama's federalized medical insurance system starts the transition away from private medical care and toward Obama's endlessly promised "universal health care." This has always been the sine qua non of planting a true, managed-market economy in the U.S.
Obama's refundable tax credits are direct cash transfers from the federal government. This would place some 48% of Americans, nearly half, out of the income tax system. More than a tax proposal, this is a deep philosophical shift, an American version of being "on the dole."
His stated intent to renegotiate free-trade agreements such as Nafta is a philosophical shift. It abandons the tradition of a hyper-competitive America dating back to the Industrial Revolution, toward a protected, domestic workforce, as in Western Europe. The Democratic proposal to eliminate private union votes -- "card check" -- ensures the spread of a static, Euro-style workforce.
Eliminating the ceiling on payroll taxes changes Social Security from an insurance to a welfare program. Obama's tax credits requires performing government-identified activities, the essence of a "directed economy."
All this would transform the animating American idea -- away from creation and toward protection.
