Infinite exponential growth is something we ALL "believe" in when we put a dollar into savings and expect to get a dollar and 5c out the next year.
The problem to me seems more that we tie all sorts of OTHER structural societal constructs to this one. To the degree that if we want to feed ourselves, clothe ourselves, and ensure shelter and security for ourselves and our loved ones - those basic _biological_ needs shared by most moderately sophisticated mammals - we are forced to plug into this system and ensure it delivers on its promise.
I've incorporated that infinite growth expectation into my kid's education plans, into our family retirement plans.
This is not a they issue, this is a we issue. The systemic structure is some parts organic but many parts choice and belief driven by general people on the street.
