They are not selling at a loss though. The real issue here is that businesses such as Microsoft do not exist to serve a market or make enough money to survive and pay their employees. They exist to increase the value of their owner's shares. This is predicated on an unsustainable model of continual growth, with the expectation that every market they operate in can produce high margins and endless expansion. But demand is not infinite and persistent high margins are the exception, not the norm.
