Krauthammer says:
For a century, an ambitious, arrogant, unscrupulous knowledge class -- social planners, scientists, intellectuals, experts and their left-wing political allies -- arrogated to themselves the right to rule either in the name of the oppressed working class (communism) or, in its more benign form, by virtue of their superior expertise in achieving the highest social progress by means of state planning (socialism).
Two decades ago, however, socialism and communism died rudely, then were buried forever by the empirical demonstration of the superiority of market capitalism everywhere from Thatcher's England to Deng's China, where just the partial abolition of socialism lifted more people out of poverty more rapidly than ever in human history.
Just as the ash heap of history beckoned, the intellectual left was handed the ultimate salvation: environmentalism. Now the experts will regulate your life not in the name of the proletariat or Fabian socialism but -- even better -- in the name of Earth itself.
I think that just about sums it all up. It is endlessly fascinating and dismaying to me that so many people seem to want to be controlled.
