Hey, I'm glad people go into the trades, and I'm glad people are willing to do important but sometimes dirty jobs like plumbing and garbage collection.
But claims about "high salaries!" and "get rich being a plumber!" and "six figure starting salary right out of the gate in the trades!" are greatly exaggerated and are offered commonly across social media and various other places without any evidence or connection with reality.
In general, broad level data show a direct stair step down in salaries, with Doctorate / professional degrees at the top, then Master's, then bachelor's, then trades / associates, then high school, then no high school (https://collegefinance.com/plan/trade-school-vs-college-degree-salaries-who-makes-more). Now, obviously, these are distributions and not all high school drop-outs earn less than people with professional degrees, but, on average, financially you are better off the more education you can get.
And going to college will open more doors and give you more opportunities for success, even if you are interested in the trades. Want to go into firefighting? Great! We need firefighters. If you go to college first and study fire protection services and management, you'll be primed to move up the career ladder (ha) more quickly than your peers who will max out earlier.
If you are considering the trades, look carefully at your local trade school. They will provide reports that show expected first-year earnings and average earnings in the trade. And then go and do it for two or three weeks with someone who does it for a living and see if you and your body can hack it.
