People who research human health and human behavior are constantly demonstrating the importance of social status.
Take a population and look at those with lowest rate of reproduction, lowest amount of social network, highest risk of loneliness, suicide, and what you get is a correlation to social economical status.
Take a population and measure stress hormones, and the output correlate to social economic status. Take a similar population and look at health outcomes over a large period of time, and the outcome is directly correlated to social economic status. Just a few weeks ago there were a paper showing that the outcome of defibrillation by doctors in hospitals is influenced by the patient social status. The higher the status, the more time the doctors spent in the room and the better the outcome was in shocking the patients heart. Low social status is predictor for slow recovery rate to injuries, and high social status has the opposite effect.
Even in biology we can see the effect clearly. Take a group of female students and their reproductive systems will sync based on social status. There is similar research that links male hormone levels directly with social status changes.
If we compare people in a very rich country with people from a very poor country, the people the share most similarities are those of the same social status, regardless of the actually wealth. It is sometimes refereed to as the paradox of welfare.
