I think they are probably right, but former central bankers like Paul Volcker and Alan Greenspan would warn that a 5% inflation target is ultimately unsustainable. People can be happy with a stable 2% target (which is too low to notice), but 5% annual inflation would eventually become 10%, and 10% would eventually become 20%, and then the US would face another deep recession, like in 1982, or even more unpleasant alternatives.
还有人说，这一问题会自己解决，至少在美国是如此，只要把年度通胀目标从2%提高到5%，因为囤积现金者所面临的实际购买力的如此大的损失将激发所需的实际投资提振。我认为这些人可能是对的，但保罗·沃克尔和艾伦·格林斯潘等前央行行长会警告说，5%的通胀目标是完全不可持续的。人们乐于接受稳定的2%目标（这个目标很低，根本不会引起关注），但5%的年度通胀最终会变为10%，10%最终会变为20%，到此时美国将面临类似1982年的新一轮深度衰退甚至更糟糕的局面。
