So you're saying personal finance is different from government finance. Bingo. Though you and I could carry a constant X percent of our income as debt for the rest of our days. If you're in business you probably are.
Small business is better off debt free, as debt takes from future consumption and unless you are growing at sufficient rate (and your debt is getting smaller as a percent of your income) you're better off keeping it as low as possible.
You could always become a primary dealer and get unlimited credit at 0% from the Fed. They do it all the time.
Maybe, maybe not. Holding cash and using credit for investment has it's advantages for any size company.
Great, let's leave that to "companies" and not allow the evil government to hold the slaves (taxpayers) accountable for their misdeeds.
