Ask HN: How do non tech (business) folks get rich these days?

I am wondering about this question lately. I have been in the tech for a decade now. I like writing code, designing solutions. But,slowly I am losing interest in coding. There is also tremendous increase in CS graduates, bootcamp grads, data science grads etc. You have to compete with 30 to 50 people everytime you look for a new job. Competition is good but I feel like it's too much hassle when compared to getting rewards I am wondering what kind of business skills a person should achieve? Sales, product management, Finance, marketing? Would a MBA degree help in acquiring these skills? What about MBA from top schools if are early 30s? Does evening MBA from Wharton/UCLA count? Any suggestions?
