The Problem

The 401(k) was designed for a different kind of career.

The 401(k) was built around assumptions about how careers work: long tenure, predictable income, a clear retirement date. For most working professionals today, those assumptions no longer hold.

The result is a gap between what the 401(k) was designed to do and what it actually does for people with growing incomes and multiple financial priorities.

What's Inside

What this brief covers.

  • The structural assumptions the 401(k) was built on — and which no longer apply
  • Why contribution limits, investment options, and withdrawal rules create real constraints
  • Five realistic approaches when the 401(k) starts working against you
  • A real example: an engineer with $380K in balance facing a flexibility decision
  • What decisions require action before a job change or income shift
  • The stop line: when to bring in a financial planner
The Example

A real professional. Real numbers.

Every Plain Brief is built around a specific person in a specific situation — not a hypothetical.

The Example
David — Engineer, $195K→$235K, 9yr tenure, $380K balance

David had done everything right by the rules of the 401(k). What he had not done was evaluate whether those rules still made sense given how much his financial picture had changed.
