Amazon is the exception. Bezos is very smart in training investors to look at the value of their investment in other ways and that company profitability is NOT one of them.
In the majority of corporations the pressure is immense to be profitable, stay profitable and increase profitability. Very few CEOs/BODs have the backbone to resist that.
Do you have any evidence to support this claim? Why does Microsoft Research exist? Why is Google sending balloons over New Zealand? Why does Costco pay their employees above minimum wage?
