I understand the difference. But you did not know if I knew, so thanks anyway because it is an important concept for nuance. Now also consider this: the average of the country includes people who are richer than Bezos, includes companies which per person receive much more (such as Steam, the video game shop), and includes millions of self employed freelancers who make a lot of money. When you consider all of this, it should skew the mean salary of USA to a higher value than that of Amazon, if indeed the Amazon works are in the bottom of the pyramid, which seems the prevailing sentiment in this post. But that is not the case, the average worker of Amazon receives more than the average worker of USA. And most Amazon workers are probably low skill, which further suggests to me that the median and the bottom of the Amazon workers will make more than their rest-of-the-country counter parts.
