Of course, business culture in the United States does not differ from business culture in all other countries in just the same way. Different countries may have their own business cultures which will, because they are different, differ from the US business culture in different ways.
One way in which the US business culture differs from many other countries’ cultures is in its extreme competitiveness. In Japan, for example, the business culture is generally somewhat less competitive. People within a company do not tend to compete as openly with one another and there is more of a set pecking order within the company. By contrast, in American companies, people compete for promotions. There is no standard practice of promoting people due only to seniority.
Another difference between the US business culture and others is the idea of superstar CEOs who are paid huge salaries. In the US, CEOs are paid very high salaries and are often seen as indispensable to the company. By contrast, in places such as the Scandinavian countries, there is much less of a disparity between CEO pay and that of the average employee.
In these and many other ways, American business culture differs from that of other countries.
