During the New Deal efforts were made to help the homeless. For example, many thousands of impoverished youth--who were riding (and living) on trains and looking for work--were given employment, food, and shelter, in the Civilian Conservation Corps. Today, such an idea would be shouted down as "godless communism!" So, with that avenue shut down, we craft other policies and actions to address homelessness--like arresting people for offering food to those in need.
Welcome to the Reverse New Deal: An all-out attack on the homeless.
