Most people who go for more degrees believe they can get better job at the end of the day. People that only go for more degrees in a stare with high unemployment rate are they doing right thing by putting all their focus on academic because this is the only thing they can do best.
This use to be the way and pattern for wealth in the past but I don't think that how many degree that you have now can be the prima facie factor to riches,.Degree is good because it gives you an advantage to access better profiting measures that can help you climb but really you don't need a job with WHO or UN to be rich.
With the advent of social media and internet, many influencers have broken some many financial records. You need a degree but that is not what you need to financial glory. You need the right contacts and placement to be able to attract that spike to financial status. Living ready is the ultimate.
