The Metropolitan Museum of Art’s decision to raise its admission price from $15 to $20 has Christopher Knight thinking: Why such a puny increase when the Met could really stick it to its customers? “It’s 2006! America has been through Reagan, Bush, Clinton and another Bush. Whether it’s health insurance, schools, campaign funding or any of the arts, liberal concepts of public responsibility have been out of fashion for a quarter-century. Didn’t the Met get the memo? Americans want things fully privatized.”
