I can't imagine a more succinct description of everything that's wrong with modern conservatism.
One of the most inscient observations between classic Liberalism (nee "progressivism") and classic Conservatism is this: Conservatism places a strong emphasis on the fallibility, the corruptibility, of man in relationship to power. Classic conservatism (I have to keep writing that because modern "conservatism" is rife with examples of people who continue to be deeply corrupt, yet continue to get gigs on radio and in print) allows for redemption, even forgiveness, but always with checks and balances.
Liberalism, in contrast, places a strong emphasis on man's capacity for redemption, for doing good, and this often translates into a firm belief that if we get the good people into the best places, they'll be able to sort everything out.
President Obama has spoken about this split himself when discussing with David Brooks his reading of American theologian Richard Neibuhr. Neibuhr, who described himself as a liberal despite his deep Christian roots, believed as many do that political power corrupted, and prescribed certain paths one could take through the political process to make use of the evil you must weild to undo greater evil, and get out with your soul intact. More than once, President Obama has described this as the course he has undertaken.
Beck's rant falls into the Neibuhrian trap, but in an odd way, backwards. He wants a radical overthrow of the American Way, to replace our current business practices in the hopes (and Beck uses the word "hope" on his radio show about as often as Obama did during the election cycle) that if we get good businessmen running the right businesses, then they'll make not just the economy, but our moral structures all right.
Maybe Beck's right, and for the first four to six years of his business the entrepeneur wakes up and says, "Yeah, competition is great!" But eventually the war becomes wearisome. Whether we argue this is sin or a relic of our Darwinian heritage, at some point when we have enough food and water and shelter and family, we come to believe in our own just deserts. The businessman turns to his neighbor, the politician, and says, "I've been here six years; I'm part of the tax base. I've paid my dues to the fire and police and water and government. Doesn't my business deserve protection from this kind of disruption?" A few excuses later, a Deal is made.
This doesn't feel "evil" to either man: they're doing themselves favors, and in the process protecting their community from the turmoil of job, locale, and economic dislocation. Homo Libertarianus is no more realistic than The New Soviet Man.
There's been a lot of analysis in modern economic literature about the difference between Homo Economicus and Homo Sapiens, about the "ideal, calculating, opportunity-maximizing agents" of traditional economy and the way real human beings respond to incentives. But much of that has been about short-term exchanges of offer, incentive, and reaction. What we don't see is how one's own incentives change as one ages, as circumstances change, and how these incentives become a slow poison we rarely resist.
