No they don't, this is a myth that has become perpetuated in recent years.

Mike Rowe might mean well by writing articles like this, but the content is a lie. The median salary of a welder in the US is $40,240 a year according to the BLS. People are essentially selling an entire generation a load of BS in order to flood the market with cheap labor instead of paying them more.

There are some welders who make $100k a year, but they are several standard deviations above the mean. Those $100k/welders are like the $5MM/yr programmers. Yeah, they exist, but only in the top 1% of workers.

I don't want my kids to be tradespeople. I watched 2008 destroy the careers of every tradesperson friend I had, along with nearly wiping out my family's (second-generation) construction business. I had talented friends in their early 20s that were forced to move back in with family after having their work hours cut to 2-3/hr a week (but they had to report to work everyday). The ones with family safety nets went to college, those without joined the military.
