I'm choosing not to use wealth because wealth is a function of both time and income. Not everybody on Hacker News is the same age so it's hard to normalize; someone might reach that threshold if they were elderly even if their income was modest. I would understand if you disagreed though.

I think your value for income is for household income, not for individual income. My quick Google of top 10% individual income for the U.S. says it's $155k, which is well within the range of incomes for senior developers and other techies in the major metros even outside the tech hubs.
