Dan Luu wrote a blog investigating this exact comparison and also didn't have good enough data to draw a strong conclusion.

Yeah, you have this stereotype that you have partners at white shoe law firms who all went to Harvard or Yale and all the other lawyers doing real estate closings from an office in a strip mall.

In practice, there are plenty of lawyers who are in-house counsels for large companies, own successful law practices in smaller cities and large towns, etc. who make decent money often in moderate cost of living areas.

This is old data, and not really conclusive, but it indicated that things were heading that way in 2016. I don't know of anything that would have changed that trend, FAANGs are even more of an outlier now I'd guess.
