Saving grace. United States, excess savings

The given graphs detail the amount of extra savings in the 2020-2021 timeframe, as well as monthly earnings and expenditure in a decade starting from 2010 in the United States. These diagrams are measured in trillion dollars. In general, saved money increased tremendously in only a year, indicating that people attempted to stockpile their resources to overcome the pandemic. Meanwhile, both income and spending rose steadily, though there were fluctuations in the final period. For the first graph, the exceeded savings started to accumulate in January 2020. Only two months later, the data witnessed a huge spike, which brought it up to over 1. 5 in the first year. Subsequently, it continued to soar to merely 2. 5 for another four months prior to stabilizing in the remaining of 2021. In the interim, both earnings and expenditure registered upward trends. In particular, within a decade, the former climbed from slightly above 0. 8 to precisely 1. 2, while the latter skyrocketed by about 0. 6 from around 1. 0. However, from 2020 to 2021, they faced wild oscillations as spending bottomed out at exactly 1. 0, as opposed to income peaking at 2. 0.
