Earlier quoted context omitted.
Why does the US have higher depression rates than any country in Africa then? Aren't there a lot of people there under financial stress?
Just spitballing here, but a culture which focuses more on individualism, less emphasis on family and community. People disown their families over petty things like political differences, don't engage in their communities because they're shut up inside watching TV all day, then find themselves without social support networks to help when they're feeling down.
To be fair, political differences are a result of moral and ethical ideology. It's fine to not involve yourself with someone whose ideology is antithetical to goodness as subjective as it may be for some.
I will never understand someone who says political differences are petty. Thinking that the traffic light's hue of yellow is a shade too light or dark is petty. Thinking that pregnant women should die because the unviable fetus their carrying is more important than they are is not petty.
