Hoover didn't "meddle" in anything. Sheesh FReepers need to retake U.S. History 101.
Discourage liquidation of unviable businesses;
Inflate the money supply;
Enforce artificially high wage rates;
Enforce artificially high prices;
Stimulate consumption and discourage saving.
Following the 1929 Stock Market Crash, the administration of Republican President Herbert Hoover faithfully followed the five steps outlined by Rothbard in the name of economic "recovery." Disdaining what he called the "leave-it-alone liquidationists" who urged that the market should take its course, Hoover initiated a series of wage and price controls, bailouts of failing firms, and public works projects. In 1931, the Fed injected more money into the economy, but the economy weighted down with the additional burden of billions in new federal "relief" spending refused to revive.
As unemployment and desperation ravaged our nation, Franklin D. Roosevelt was elected in 1932 on a platform properly castigating Hoover for meddling in the economy. Once in power, FDR immediately discarded that platform, choosing instead to build on and expand the Hoover administrations socialist initiatives with predictable results.
For the real history backed by factual proofs, I repeat, READ "A Patriot's History of the US" Man, whatta great book that dissects and discards all the liberal historical publications and clarifies who did what when! It's by far the best, most convincing and logic-based US history book ever! History 101 does not hold a candle to this work. Buy it (Amazon has it) and learn the facts.
Perhaps you weren't paying attention to your professor in History 101.
