Yeah, I'm not so sure about this. The author is making a lot of assumptions without providing any support for those assumptions. I won't go through it line-by-line as it would take too long, but I think this article warrants genuine and thoughtful consideration on a line-by-line basis.
Maybe the author should visit modern day New York or Boston. Many places still do not have air conditioning (like my house) and are poorly heated, often with the exact same radiators that have been used for over 100 years. The fuel source has changed from coal to oil, but it's still a boiler in a basement still using the exact same pipes and exact same radiators. The radiators in my house are over 120 years old.
Why would you listen to the radio or watch TV? The author must enjoy being bombarded with material that keeps him stuck in the consumer driven American nightmare. How awesome is Skype and e-mail? So awesome that people pay to learn how to disconnect and long to not have a phone as a shackle. He just keeps racking up points in favor of Rockefeller.
He never touched on wealth so great that you never have to work on things you don't enjoy. Wealth so great you can buy politicians. Wealth so great you can dine anywhere, go to any play, any museum, and have access to any experience that is available. Wealth so great you can finance any charity you wish, buy a wing at an art museum, and generally have a say in the direction of anything that interests you. I'd give up e-mail and my existing lack of A/C in a heartbeat to change places.
