4. Federal jobs could provide socially useful goods and services. During the Great Depression, the Works Progress Administration (WPA) and Civilian Conservation Corps (CCC) were public employment programs designed to put Americans back to work after the national unemployment rate reached 25 percent. These programs, implemented under the Roosevelt administration, provided socially beneficial goods and services that benefited all Americans. Some of our national parks — Zion, Glacier, and Shenandoah — received substantial work contributions from employees of the federal jobs programs. The Blue Ridge Parkway was a federally funded and staffed infrastructure program. A new federal job guarantee could undertake similarly bold and much-needed public-works projects. The American Society of Civil Engineers gave the United States a D+ in infrastructure and prices necessary repairs at $3.6 trillion. This lack of investment has lowered employment rates, cost businesses sales, and reduced incomes for American families. Make no mistake, these are government choices. They could choose instead to hire unemployed workers to repair bridges, maintain roadways, and update power grids. Likewise, Bill McKibben just called for us to “declare war” against climate change. With climate change being perhaps the largest threat to our well-being, bold action is needed. The job guarantee program would create the capacity to do just that. Professor Robert Pollin of the Political Economy Research Institute calls for scaling up the transition to a green economy, which would create millions of new jobs along the way. He and his colleagues estimate what a Green New Deal would look like, and find that a transition to a green economy would amount to an estimated $200 billion in investment annually, resulting in a drop in “US emission by 40 percent within 20 years, while creating a net increase of 2.7 million jobs.” In part, this is due to the labor-intensive nature of energy efficiency and other “green” investments.
