I think you are probably correct, but must point out that central heating and air (I didn’t use AC for 23 years, though I had a big unit on the side of my house), kids aren’t necessary. I am fond of electricty and tech gadgets, though, because they make minimalism and living far from ‘society’ much easier and more pleasant. Unlike most consumers, I do not upgrade often and usually buy used PCs now. If we make it more socially acceptable to not have kids or to live in small quarters or to be cheap, then maybe others will fall in line. I get a lot of grief from others, but am stronger, more independent-minded than others. I guess we need more awareness out there to counteract certain opinions. Appealling to their slefish side is usually the way to go. Trying to sell altruism, something that goes against human nature, doesn’t work well. Trains in the city are excellent ideas. Sending them to the suburbs or rural areas are not always good ideas and people in those areas often hate that idea. At the end of the day, we can only control ourselves and if others see that our lives are better, more content, then they are more inclined to learn by the example we set. People often call me a cheapskate until they see that I am usually less stressed than they are because I don’t have to worry about the bills or upkeep they have to worry about - or about what others think. “Saving the earth” might sound to many a bit like you intend to use force.
