The only trades who are millionaires are those who started a business that became successful and employ others, probably at least a dozen staff. That makes such folks no more likely than 1 in 12 (assuming their business lasts and they don't regress to the mean). That's not the average tradesman today, and likely to be even less frequent in the future. The average Joe Tradesman never makes no more than $50K per year and has to retire in his 50s because the hard physical work (and inadequate health care) has worn down his body and he can no longer keep pace with 25 year olds. That's not a winning career strategy, especially in a future in which the rise of product disposability and building with modular components will simplify and reduce demand for much of today's trade work.
