Indeed, in virtually all advanced economies, high levels of inequality, strains on the middle class, and aging populations will fuel political strife in a context of unemployment and scarce fiscal resources. As these old democracies increasingly turn inward, they will become less helpful partners internationally – less willing to sustain the multilateral trading system and more ready to respond unilaterally to economic policies elsewhere that they perceive as damaging to their interests.
在几乎所有的发达经济体中，高度的不平等、中产阶段的压力和人口老龄化等问题，再加上失业和财政资源短缺，将激化政治冲突。随着这些老牌民主国家逐渐将重心转向国内，它们在国际上发挥的作用将更小——它们维护多边贸易体系的意愿会减弱，而更倾向于单边应对它们认为会损害自己利益的别国的经济政策。
