Except Google is literary printing money for everybody else in the group. Amazon is cashflow-from-operations positive, but nowhere near Google. More importantly, Amazon attempts to enter HUGE, developed markets, not the non-existent markets (at the time) of internet retail, cloud computing or public information retrieval. The only way for Amazon to enter in those markets is if they make a serious commitment. It is my opinion that if they commit themselves to the new markets they have been eyeing in the past couple of years (b2b commerce AND logistics), investors will become very bearish, leading to a disaster for Amazon, probably even a buyout.
