"Just learn a trade."
The internet says AI is coming for desk jobs, so become an electrician. For an 18-year-old with no debt, that can be great advice. For someone in their 30s to 50s with a degree, a mortgage and loans, here's the math nobody posts.
The apprentice pay cliff
Typical ladder: $20 → $24 → $28 → $33/hr over 4 years, then ~$42/hr as a journeyman. Take-home after ~22% tax.
That's $126,048 in lost income before you ever hit journeyman pay. Your loans don't pause while you learn.
Your body is the asset
Desk work peaks on experience — you get better into your 50s. Trade work runs on knees, backs and shoulders. Many tradespeople are dealing with chronic pain or surgery by their late 40s to early 50s. Injured and not the owner? Income drops to zero.
Where the six-figure plumber comes from
The $120k number usually includes 55–65 hour weeks and paid overtime. Divide by the hours and it's a normal wage.
Burst pipes and dead panels happen at 2am on Sundays. Emergency rates are good because the hours are awful.
The real money goes to owners: $60–80k van, tools, liability insurance, workers' comp, licensing, chasing unpaid invoices.
Top trade pay is in high cost areas and union markets. Many regions pay journeymen $25–32/hr.
You hear from the guy netting $200k, not the one who left at 44 with a fused disc.
Who is this actually for?
- 18–25, little or no debt
- Can live cheap or with family for 4 years
- Likes hands-on work, healthy joints
- Wants to own a shop someday
- 32–52 with a mortgage, kids, or loans
- Existing back, knee or shoulder wear
- Expecting $100k in year one
- Running from burnout, not toward the work
- Downshift to a lower-stress role in your own field — keep the pay floor, lose the pressure.
- Freelance or consult in what you already know. Your experience is the asset; don't throw it away.
- Trade-adjacent desk work: estimating, project coordination, inspection, facilities — uses your degree, not your spine.
- Build a small side income first (see Side incomes) before quitting anything.
What they say vs. what's true
True — but trades are tied to housing and construction. When rates rise and building slows, work dries up fast. Safe from AI is not safe from recessions.
Some do. The median plumber earns around $60k. The headline numbers are owners and overtime, not a typical paycheck.
They pay you about $20/hr to learn. Great at 19 living at home. Not great with a mortgage and two kids.
Your degree still has value. Throwing out 10–20 years of experience to start at the bottom is the expensive part, not the degree.
Apprenticeship spots are competitive, often favor younger applicants, and many unions have waitlists.
