The New Deal was fundamentally intended as a modern expression of ideals set forthe one hundred and fifty years ago in the Preamble of the Constitution of the United States - 'a more perfect union, justice, domestic tranquility, the common defense, the general welfare and the blessings of liberty to ourselves and our posterity.' But we were not to be content with merely hoping for these ideals. We were to use the instrumentalities and powers of Government actively to fight for them.
All I can figure is that the severity of the Depression made FDR and his generation blind to the ideas which inspired the Founders, i.e. natural rights to life, liberty, and property. The Founders intended to strictly limit government, because they recognized that coercion is the primary means of government, and so it is antithetical to liberty. These eternal truths were swept aside by the wake of the Depression, and now we're stuck with an endless parade of charlatans and well-meaning dreamers. I just wish the dreamers would get themselves a real dream.
