I feel jealousy and status anxiety, and I feel it more strongly when I am dissatisfied with my own life circumstances. There was a time when I was unemployed for 18 months, and very close to getting a job with what I consider to be a high income. I found myself walking around on Mercedes lot looking at the cars, which is out of character for me.
I like to notice my jealousy and try to figure out what it is telling me. If I think I am feeling something valid, for example, if I notice somebody's house and feel a little jealous of how it is decorated, I start asking myself what are a few things I could do that I would like. Similar things for seeing couples do things together, families having activities together, job success, physical fitness, etc.
I don't think well-contained and well-understood jealousy is a completely evil or immature emotion.
