Running a business = / = running a country. I know it sounds intuitive that a successful businessman can "fix" the economy, but the logic doesn't back it up and neither does history.
Presidents that had business backgrounds. Almost all of them are ranked poorly among their fellow presidents. Truman being the lone except. Interestingly enough they all served in business and politics before becoming president, like Mitt Romney. No president has went straight from the private sector to the presidency.
The biggest problem I see is that running a business, your major (really only) goal is profit. If you apply that same mentality to government, then they should raise as much revenue as possible. Sure that could help lead to a budget surplus. The best way to raise revenues for a government is to increase taxes and reduce spending. That's called austerity. That's what Hoover did and he got a balance budget, but look how well that went. Tax increases are only justified when you are investing it back into the community, e.g. infrastructure, healthcare, education, military etc.
Also, CEOs/businessmen generally think of profits in quarterly, maybe yearly models. Of course there is some long term planning, but it is hard for a firm to stay afloat if it carries a short term deficit, unlike the government. The government has a much more stable source of income, so it can easy have a deficit in short term, ranging from months to even years, in order to provide for a better future. Good politicians are thinking about the next election
and generation.
. I guess Bernie is choice 2
