It's important for entrepreneurs and investors to recognize that it's the making money part of the business that is ultimately key to survival. Often this creates positive alignment between entrepreneurs as well as multiple classes of investors. However, sometimes (e.g. when a company is not doing well) it creates a zero sum situation. When this happens, as is more common than not, the rational expectation is that folk will look after their own interests. If someone acts irrationally, it's usually the entrepreneur, who bends over backwards to take care of employees and investors.
