Mark Weisbrot

There is a common perception in the US that Venezuelan President Hugo Chávez has a big media advantage over the opposition in the upcoming elections. The Committee to Protect Journalists, in its latest report on Venezuela, states that “a vast state media presence echoes the government’s positions,” and refers to the government as having a “media empire.”

From the Wilson Center’s latest report, we read: “Media coverage is not even moderately balanced.  … In television, the government’s predominance is overwhelming; it was estimated that by 2007 it controlled seven national television channels and 35 open community channels.”

Why Are College Textbooks So Absurdly Expensive?

You thought the rising cost of college tuition was bad? Then check out the rising cost of college textbooks. The American Enterprise Institute’s Mark Perry has put together this chart showing the egregious, 812 percent rise in the cost of course materials since 1978, as captured in the Bureau of Labor Statistics’s consumer price index data. The price of all those Intro to Sociology and Calculus books have shot up faster than health-care, home prices, and, of course, inflation.
