The consumer credit available to Americans is being used to pay bills, not improve quality of life.

All Americans, according to this RAND study, have lost income during this period of COVID-19. The higher the income the less income lost. 

With government SUBSIDIES, lowest-income Americans did improve their outcomes. Working with percentages in this instance can be tricky because 4 percent of higher-income households may actually be the same amount of monies received by the lowest incomes receiving 12 percent.

...Households' methods of coping (click here) with these difficulties vary across the income spectrum. A widely cited survey question from the Federal Reserve asks how respondents would pay an emergency expense. To take into account the widespread, unexpected job losses and financial downturn associated with the COVID-19 pandemic, we modified this question to ask people who are in the midst of an emergency—those who reported difficulty in paying their bills—how they are dealing with expenses.

Among households that are struggling to make ends meet, we found that approaches vary significantly across the income spectrum (Table 1). Unsurprisingly, low-income households have few options. They report borrowing from friends and family, selling possessions, and simply being unable to meet expenses. Consistent with these findings, evidence from other surveys reveals rising food insecurity among low-income households.

Middle-income households report using formal credit: putting expenses on credit cards with the hopes of paying the debt off over time, using bank loans and lines of credit, and, in some cases, taking on payday loans. We found fewer reports of payday loans among the low-income group than among the middle-income group. Although this difference was not statistically significant, it might reflect the higher rates of job loss among low-income workers, as documented in other surveys; without a job, a payday loan is not an option....

In Table 1 of this RAND study, it is very obvious all levels of income in the USA are using credit to pay their bills. So, while the Fed is creating a better financial environment for the use of credit in the USA, the consumers of credit are using it at this time to pay bills and not to improve their quality of life. That is a concern for the future. If there is significant credit building up with consumers that means they may be using bankruptcy to protect their financial position in times to come. That SURVIVAL STATUS will effect their spending behavior now.
