The takeaway is, maxing out retirement accounts like a 401k and dumping savings into paying off the primary residence mortgage are ways to accumulate net worth without accumulating "above-typical" assets.

What do you mean by "typical assets"?
For applicants who report total annual parent income up to $125,000, we generally consider "typical assets" to be an adjusted total net worth of less than $300,000. Adjusted total net worth usually reflects the sum of the following amounts:
Cash, savings, checking Investments Home equity, capped at 1.2 times annual income Equity in real estate other than the home Business net worth
We do not include formal retirement assets (401k, 403b, IRA, Keogh) in our analysis.
