and possibly Amazon slowly (or quickly) to go to cack - happens in other cases. The founders leave and the new management stuff it up.

Yeah, you are right, sometimes it goes to cack with the new management. However, in Amazon's case, I think they built the wealth and diversification to the point where even for the most incompetent of managements it would take years to run down. From what I've read and seen the new CEO is quite good, in fact, he took AWS to the heights that it is now which is the biggest Amazon's revenue stream.
