"Conservatism, though a necessary element in any stable society, is not a social program; in its paternalistic, nationalistic, and power-adoring tendencies it is often closer to socialism than true liberalism; and with its traditionalistic, anti-intellectual, and often mystical propensities it will never, except in short periods of disillusionment, appeal to the young and all those others who believe that some changes are desirable if this world is to become a better place. A conservative movement, by its very nature, is bound to be a defender of established privilege. The essence of the liberal position, however, is the denial of all privilege, if privilege is understood in its proper and original meaning of the state granting and protecting rights to some which are not available on equal terms to others."
—— F. A. Hayek, 1956 Preface to "The Road to Serfdom"
That's a pretty good and thought-provoking observation by the "father of modern Libertarian thought" and it's a guidepost for examining the plethora of government-funded and government-enforced privileges of 'ownership' -- from the equities markets to the military's global reach in service to "owners" not otherwise served in other countries. When I examine the manner in which we've toppled or propped up regimes all over the globe in the last century or more, I see nothing more consistent than the DEMAND that those regimes enact and enforce laws granting privilege to Owners - Global Corporatism. From the Afghanistan pipeline an the Iraqi "oil laws" all the way back to the Marines sent in to protect United Fruit's privilege to enslave 'workers' in Central America.
It's a theme that's COMPLETELY borne out in every act by Cheney/Bush and Conservatism (even Royalists!) over our entire history.
Hayek's quote stands for me even today as the most pithy and succinct distinction between liberal and conservative stances that I've seen. Like any such "bottom line" however, it's not as much an argument as a conclusion --and is useful to me mostly in the degree I'm familiar with the abundance of examples that lead to it as a conclusion. I find it nearly impossible to deny with any rational thought process whatsoever.
