A recent US Census survey (which allows multiple responses) reveals that 2/3s of respondents are meeting at least some of their spending needs solely from regular income sources (salaries from their jobs). Notably, this means that 1/3 of respondents have no work income.
Over 1/3 of respondents are relying on borrowing from credit cards or loans and 27% are relying on savings or selling assets to meet their needs.
The survey also reveals that 15%+ of the respondents are relying on some form of government assistance to help meet their needs.
In a healthy economy, consumers would be able to meet almost all their spending needs from the regular pay provided by their jobs.
