Boeing and Intel also were very successful companies until they weren't. Arguably the decisions that led to that were made years if not decades before there were any publicly obvious signs of their demise.

I bet the there plenty of people saying the same things as you are here and in other threads. Of course I'm not saying this or any other specific action will somehow lead to Amazon's demise but saying stuff like you did in the other thread:

"I’d be inclined to let the people who successfully built Amazon into a 2.25 trillion dollar company continue to do their thing"

Just seems a bit silly...

Regardless, Amazon might have other incentives than maximizing the wellbeing and of their employees in no way does that conflict with them being very successful.
