Green socialism often combines bad science with bad economics. From Thomas DiLorenzo at lewrockwell.com:
Upon taking control of the U.S. House of Representatives the first thing America’s Marxist Party did was to propose a Soviet-style, communistic destruction of American capitalism labeled a “Green New Deal.” The Party chose as its spokesperson for this totalitarian venture a young woman named Sandy Ocasio who grew up in one of the wealthiest enclaves in America, Westchester County, New York, but who decided to lie about this to get into politics by calling herself “Alex from the Bronx.” Sandy sounds like a poorly-educated-but-well-indoctrinated young communist with a ninth-grade mentality. She proudly labels herself a “democratic socialist” but as Ludwig von Mises explained, there really is no difference between communism and socialism: they are both attacks on private property and economic freedom. She seems clueless about just about everything she talks about in public, whether it is the Constitution, especially the economy, the structure of government, history, etc. This is the person the American Marxist Party has chosen as its front person in its proposal to destroy American capitalism, prosperity, and the American dream forever—and to give itself totalitarian control over virtually all aspects of American life.
The first thing to understand about the proposed “Green New Deal” is that the first New Deal not only failed to end the Great Depression but made it more severe and longer-lasting. Its only “success” was in creating endless patronage opportunities and levers of political bribery and extortion for the Democratic Party, opportunities that the Republican Party happily embraced whenever it could to expand its own power and wealth in the succeeding decades. The proposed Green New Deal would do the same, only many orders of magnitude worse.
