ARTHUR BROOKS: "A menudo me preguntan si EEUU se está convirtiendo en una especie de democracia social a la europea. Mi respuesta siempre es: 'no, porque ya somos una democracia social a la europea'. Desde la progresividad de nuestro sistema impositivo hasta el porcentaje del PIB que supone el gobierno, pasando por la regulación de las empresas, Europa no tiene nada que envidiarnos."

In 1938—the year my organization, the American Enterprise Institute, was founded—total government spending at all levels was about 15% of GDP. By 2010 it was 36%. The political right can crow all it wants about how America is a "conservative country," unlike, say, Spain—a country governed by the Spanish Socialist Workers Party for most of the past 30 years. But at 36%, U.S. government spending relative to GDP is very close to Spain's. And our debt-to-GDP ratio is 103%; Spain's is 68%.

At first blush, these facts seem astounding. After all, Spanish political attitudes differ dramatically from our own. How can we be slouching down the same debt-potholed, social-democratic road as Spain? There are three explanations, all of which point to a worrying future for America.
