Why do people complain so much?

Because they are dissatisfied. Human beings generally complain -- or make their dissatisfaction known in a verbal manner -- when they feel dissatisfied with:

• life in general
• a job or employer
• the amount of money they earn
• the state of their relationships or home life

Humans also voice dissatisfaction when they feel they:

• are being treated unjustly or unfairly
• are burdened with more work than another person (including a live-in partner or spouse)
• feel stressed or are experiencing pressures
• lack the money or ability to change their situations in a meaningful way.

Other people complain about their circumstances, despite the fact that they have enough money, adequate housing and transportation, good family support, a thorough education with a good salary at a great job, and seem to have "every advantage" in life. Psychologists say that people with these circumstances may have feelings of "entitlement" that makes them believe they are "owed" more in life. Nothing feels meaningful or satisfactory, no matter how much advantage they have. In some cases, underlying depression can be behind this thinking. Or, sometimes, people who feel entitled lack empathy-- they cannot put themselves in other people's shoes and thus, feel grateful for what they do have.
