If free, unlimited energy were available today we would likely see the largest economic boom the world has ever seen over the next 10 years. Yes, "blue-collar" workers may lose their immediate job, however the increased demand for employees in other sectors of the economy due energy cost going down to zero would be staggering. These workers may find jobs immediately in other sectors or see opportunity in education. There are literally thousands of new jobs that would emerge in major sectors of the economy overnight. It would be the single greatest economic opportunity in human history, not some grand tale of sadness for people that lose their job. The entire country and world would be instantly more productive and better off.
