Economic hardships cause emotional distress, and you can't rationalize feelings. Your civil expectations probably match your income level, but not that below you.
E.g. Not getting enough sleep because your poor neighborhood is a ruckus provokes bad mood, chronically.
My civil expectations match what I expect from other people and how I treat people in the world. Has nothing to do with my income and is based on how I was raised by my parents to treat people you interact with in the world.
I've done hard labor (construction, landscaping), I've done food service (sandwich shop) and I've done lots of white collar office work. Wealthy people can be nice and decent to people who have a much smaller income AND vice versa.
