And to highlight your second point you are once again being irresponsible and immature. I do live a simpler life and a much more responsible one while still operating within modern society just fine (yes, I have a respectable paying job and commute to work). That's the main problem with people like you who will go down with our current society proclaiming it the greatest. There is simply no compromise, which there needs to be in order to ensure there are societies in the future, and better ones at that. There are myriad ways society as a whole could be more sustainable and efficient, such as through the increased use of public transportation, better bike access, more walkable streets, more mixed-use buildings, green urban design concepts, funding for better education and research, the list goes on! The problem is not that it's hard to make all of this happen, it's that people like you, so rooted into thinking there is nothing better than your comfortable way of life, make it hard.
