The waxing and waning of the dollar is strongly linked to the ups and downs of the credit cycle.

For instance, the moon's waxing and waning have been used to symbolize the impermanence of life, and the full moon often signifies reunion and completeness.

例如，月亮的起伏被用来象征生命的无常，而满月通常象征着团圆和完整。

名人——地球上的明星——扮演的角色也差不多：我们将他们视为榜样或警示故事，并将他们的起起落落视为公众舆论的晴雨表。
