Abundance explains that our problems today are not the results of yesteryear’s villains. Rather, one generation’s solutions have become the next gener­ation’s problems. Rules and regulations designed to solve the problems of the 1970s often prevent urban-density and green-energy projects that would help solve the problems of the 2020s. Laws meant to ensure that government considers the consequences of its actions have made it too difficult for government to act consequentially. In the last few decades, our capacity to see problems has sharpened while our ability to solve them has diminished.
