Because FDR bought votes with “job programs,” but the federal government today is so large, bloated, and hamstrung by its own bureaucracy that there is no way it would be able to do that today. Plus monetary policy is very, very different.
The economic situation of today is not like the Great Depression. We need a fever to cure our illness.
What is the difference between buying votes with “jobs programs” then and buying votes now with Obama phones, free tuition, bailouts, and “free healthcare”?
