You are SO right. Unfortunately I think many cannot relate until they do something similar to what you did at Amazon. That type of exit also applies to me. I walked away from a great business and an enviable lifestyle. I have never regretted this move. My life is totally different now, including more happiness, peace of mind, all that.
While there are circumstances that prevent many from doing what you did, what I did, I think there is a misconception. The net worth or income required to seek a life outside the monolith of consumerism is not as high as imagined.
