Many of my friends are in the trades (I would be fascinated to know if that's common on HN, my hypothesis is that it is not) and the unspoken thing in a lot of "go into trades" rhetoric is that most trades people either get into management as fast as they can, a small amount start their own business and a share of that small amount are very successful, or a large amount of people trade $$$ for future health problems (not just joints, many of the materials used in trades are awful and many never wear proper PPE). It's important to look at the trades without the veil of blue-collar romanticism; the trades can be lucrative but tradesmen will be very quick to give you the tradeoffs.
