The best point made in the article is that the danger to the United States comes from its track record of success:<p>"Mancur Olson . . . was prompted by what he thought was a strange paradox after World War II. Britain, having won the war, slipped into deep stagnation, while Germany, the loser, grew powerfully year after year. . . .<p>"Olson concluded that, paradoxically, it was success that hurt Britain, while failure helped Germany. British society grew comfortable, complacent and rigid, and its economic and political arrangements became ever more elaborate and costly, focused on distribution rather than growth. . . . The system became sclerotic, and over time, the economic engine of the world turned creaky and sluggish.<p>"Germany, by contrast, was almost entirely destroyed by World War II. That gave it a chance not just to rebuild its physical infrastructure but also to revise its antiquated arrangements and institutions . . . with a more modern frame of mind."<p>On the other hand, Britain is arguably not very far behind Germany even today, as Britain later had opportunities to learn from failure. Definitely a country that learns to embrace learning from failure (even the relative failure of not always being the best, while still being quite good by world standards) is a country that can keep making progress. I'm not counting out the United States yet as a country that can learn to do better, especially because the United States is still very receptive to immigrants from all over the world who feel an urgency about bettering their lives.
