I think it's evil the amount of energy and resources that go into creating unnecessary desires in people in order to cultivate a consumer class. It's time to reap the benefits of our technological advancements, by working shorter weeks, finding less expensive ways to build shelter (houses), and becoming more proficient in local food generation.
Ways to do these things have been around for decades, but it's not in the interest of the producers of homes and employers to do them. Look into some of the inventions by R. Buckminster Fuller. He invented a house that cost thousands, easily transported, made of aluminum, and sturdy, but it never caught on. Probably because he didn't spend time marketing it, but the mobile home and large home manufacturing companies…
