◆ The honest take — what these numbers actually mean
Pre-Med (Biology)
Pre-Med is bimodal. If your kid gets into med school (~40% acceptance per AAMC) and finishes residency, the median attending salary is $240K-$450K. If they don't, they have a Biology BS — starting at ~$46K, peaking around $86K. Same major, two very different financial lives.
The decision isn't "is Pre-Med worth it?" It's "what's the plan if med school doesn't happen, and what does $280K in med-school debt look like if it does?"
Mechanical Engineering
ME is one of the most consistently profitable BS-only majors in 2026. $76K starting, very low underemployment (~7% per Federal Reserve), and broad applicability — manufacturing, aerospace, robotics, energy, defense.
The trade-off: less explosive upside than CS or finance. Few ME grads earn $300K+ unless they pivot into management or start a company. Strong, stable, and not that flashy.

◆ AI disruption risk
3
/ 10 · LOW RISK
Patient-facing medicine remains highly safe — diagnosis assistance and admin automation help doctors, not replace them. Lab/research biology has more exposure (data-heavy roles in pharma R&D and bioinformatics).
5
/ 10 · MEDIUM RISK
Generative AI design tools (Autodesk Fusion AI, NVIDIA Omniverse) are reducing entry-level CAD work. Hands-on, hardware-facing engineering roles — manufacturing, robotics, field engineering — remain robust.

◆ Bottom line — one screenshot to send your kid
Pre-Med — verdict
Pick if your kid is genuinely called to medicine AND has a real backup plan for Biology if med school doesn't happen. The MD path is among the highest-ROI careers in America — but the BS-only fallback is one of the lower-paying STEM degrees. Have the honest conversation BEFORE the deposit, not after.
Engineering — verdict
Strong, stable, broadly applicable. Low underemployment, fast payoff on debt, multiple sub-specializations to pivot into (robotics, aerospace, manufacturing). Less explosive upside than CS or finance, but very few ME grads end up underemployed or in debt purgatory. A safe pick that actually pays.
