Jack Goldstone fits American global decline into a larger historical pattern:
In short a key difficulty faced by regimes in decline was selfish elites. Nations that were the richest countries in their day suffered fiscal crises because elites preferred to protect their private wealth, even at the expense of a deterioration of state finances, public services, and long-term international strength.
By ‘selfish elites’ I do not mean, of course, simply elites’ aspirations to maintain disproportionate shares of wealth and power. That ambition is a universal constant. What I wish to emphasize is that in some eras in history, elites have identified their interests with the national state and the public weal, and they have been willing to tax themselves heavily to expand the influence and resources of their nation and their government. At other times, … elites have turned into competing factions, driven by self-enrichment at the expense of their rivals and opponents, even when that meant starving the national state of resources needed for public improvements and international competitiveness.
