According to the chart in post 52, boilermakers are at 29 an hour. I don’t pretend to know all of these professions, but I do know that in my area, plumbers, electricians, and carpenters do not make anywhere near the figures you cite.
That is because your chart does not take into account the benefits they receive which is in the neighborhood of $15 per hour. This is direct benefits to them.
Even at $29 per hour that is over $60,000 per year not including benefits and the mentioned boiler makers always work tons of overtime a little a time and a half and a bunch at double time pay.
Many people would love $60,000 per year.
My numbers are from the Midwest and I know for sure the west coast is very close to the same. Can’t speak for the left coast.
My numbers are accurate. I am working on a research paper about this very subject. Everyone of my extended family is also in a skilled trade.
“...in my area, plumbers, electricians, and carpenters do not make anywhere near the figures you cite.”
Six years ago I worked a fiber-optic installation job. We were classed as “electricians” and base pay was $32/hour.
At 62 years old I was figuring that the other folks on our 8 man crew would be calling me “Gramps”. It turned out that I was only the fourth oldest on the crew.
Too few young people entering that job field.
