Faced with millions of Americans out of work, including an army of roughly 154,000 homeless military veterans seeking shelter every night, President Obama and Congress should quickly revive one of the most successful government actions during the Great Depression. That action was creation of the Civilian Conservation Corps, which the Roosevelt administration convinced Congress to support within weeks of FDR taking office in 1933. Over the next several years, the CCC hired more than three million young men to plant three billion trees in over-logged forests, repair 40 million acres of soil-eroded farmlands and create 800 state parks, according to the US Forest Service web site.
