The old saying "The market can remain irrational longer than you can remain solvent" always applies.

It really doesn't matter if you are a responsible company that takes on low/no debt if a significant number of your competitors take on debt, and their investors allow it. "Soon" is highly overrated. Amazon is going to make lots of money 'soon' unless they are wrong about future market conditions, yet their investors have given them a pass at reinvesting most of their money for growth. Entire industries can commit irrational actions for long periods of time and have plenty of analyst attempt to rationalize the situation.

Sure but the point is once the market dries up the companies will know. Thats not the same for governments who do their budgetting rather different.
