Do rich people care more about mental health?

I participate in a zoom group club with the online society I’m in and I noticed that ever since our activities became digital, most of the poor and uneducated people in our group have disappeared from our social networks. I used to be above average in our group and now I’m considered average or dumber because all the less intelligent and less educated and less wealthy people have departed from our group making me look dumber by comparison. I never understood why it seems only the rich participate in our group but my mom says only people who have all their material needs satisfied are interested in protecting their emotional health.
