I'd take the exact opposite tack. If you're making more, you can keep housing expenses that much lower as a percentage of income and still live in luxury.
This helps with addressing the correct assertion that you need to invest more than 10-15% of income if you're a high earner. That's because Social Security replaces 90% of low incomes, but as your income grows, the fraction replaced by benefits drops precipitously to 10%. You also usually have to account for higher taxes in retirement.
