I noted that the wealth gap would be larger, but it's still not enough to make the parent poster's comment accurate (filling in a few points, you have 93rd percentile ~ $2 million, 96th ~ $3 million, 97th ~ $4 million).

Of course, income doesn't map that directly to wealth, even after accounting for age (if your income derives from a salary/investments from savings, you expect to move up further in wealth than in income as you age). Those 98th percentile income software engineers won't be 98th percentile in wealth when they're 60 unless they save extreme amounts of money, but they'll enter that 9.9% if they're prudent.
