You are a smart man. Living in america, its so easy to see that we consume more, waste more, spend more, worry less, and expect the fines luxuries like its our god given rights. Most of our spending has been financed by the way. Its pathetic and this is one area thats embarassing about being an american. Our materialism and vanity is our own worst enemy. We need to calm the hell down, save more, and live below our means, not 5x above them.
Your point about insulation is a good one, and one that we should adopt, but we’d rather spend that money on granite countertops that do absolutely nothing, than make our homes more efficient. And one ac unit isn’t enough you know, we have to have huge 3500+sqft homes to keep up with the Jones’s, so I need two AC units to cool my huge palace, day and night.
We can still attain the highest quaity of life on the planet even if we do take a look in the mirror and address the problems that we face rationally.
