在国内政策方面，失败要开始得更早：从20世纪80年代的里根经济学到21世纪10年代的奥巴马医保，重大政策总是承诺过多、兑现过少，同时，根本性问题也没有得到解决。
With regard to domestic policy, the failures began even earlier: from Reaganomics in the 1980s to Obamacare in the 2010s, major policies have often overpromised and underperformed, while failing to address underlying problems.
