It also does not address the issue of welfare mothers and the men that they copulate with.
For example: Low-income stay-at-home moms, where the annual household income is less than $36,000, report higher levels of unhappiness. Over half report they are struggling, and four percent say they are suffering. Only 46 percent say they are thriving.
Okay, what else can you tell us about these "moms"? For example, which ones are married? Are the "thriving" 46% married? Unmarried motherhood is highly correlated with unhappiness.
