It is its own little universe and not representative of the majority of America. People I know who make silicon valley money by working remote coastal jobs and living here in Kansas all live in the nicest suburbs around, in 3-4,000 square foot McMansions with pools, and lawn care to mow their lush perfectly landscaped yards.
These people are making probably 200k with a working spouse. They’re in the same salary bands as local doctors and attorneys. Quality of life based on income is very different in middle America.
