Just for a point of reference, I've been a Cabinet Maker, Welder, Powder Coater, Skid nailer, punch press operator and more. Believe me, I understand blue collar. I was in my 30's before I worked professionally as a programmer.

I currently live in a town that is resource based, mining and forestry. The epitome of blue-collar. Believe me, those guys make double what I do with bonuses and benefits. Even without, they make significantly more than I do. It isn't uncommon for a worker in this town to be able to retire by 45. They work until they are offered early retirement, or, have their pensions bought out. All this with very little education beyond 'common-core' in the mining sector. Ya, they bust their asses. But they're paid for it. So, ya, you raise valid points, but I'll stick with my first hand experience. Have you ever worked blue-collar or just second had info as you present.
