Which is, of course, entirely false. President Hoover upped the interventions into the market to unprecedented, until Roosevelt came along, lengths. Roosevelt actually ran his campaign against the interventions of Hoover.
True enough, Hoover did not sit by and play the fidel, and neither did George W. Bush, btw. The question in the OP is, what would you do, and my answer is much more than Hoover, Bush II or Obama.
Everyone agrees that Job creation is issue number one. The Oddballs blame Obama for not creating jobs and in the same breath blame him for getting in the way. Presidents alone cannot create jobs, they need to work with Congress and that has been an impossible task. What I would do if I were Obama is propose major projects, as I suggested above. This will provide the business community the resolve they need to expand and hire. Knowing major construction projects lasting years have been approved in principle by the White House and Congress would do much to restore confidence in the economy and jump start growth.
Sadly that won't happen. The dishonorable opposition lead by Limbaugh, Palin, Gingrich, McConnell and Boehner don't give a shit about anything but their personal agendas. Country first my ass.
