He made a lot of good decisions. It was unlikely that an outsider would become the world's largest retailer, because others were there with existing infrastructure and knowledge, especially mail order retailers like Sears in the US or Otto in Germany. But they missed the boat. All they had to do was to transfer their catalogue to the internet and expand. But somehow they failed and a nerd with an online bookstore grew bigger and bigger because he understood the internet much better. Oh, and the mail order businesses were no angels, either. Otto has been running its own logistics company since the seventies and they are not particularly famous for high salaries. Of course, there are lots of people at Amazon who work hard and/or smart, but without the guy at the top making the right decisions, it does not work. Does it mean Jeff Bezos deserves to be THAT rich? I dunno.
