I hear that narrative a lot and I think it does a major disservice to the people interested in entering the field. Are there blue-collar workers making huge sums of money? Yes. Are most blue-collar workers making huge sums of money? No.

There is also the physical toll that gets glossed over. I know tradespeople who made a lot of money until they weren't physically capable of doing the work anymore. Some were able to focus on running the business and had trained up good people to do the actual work. Others were in a really bad place.

> but if this becomes a widespread trend there will be an oversupply of tradespeople and their wages will fall.

It is cyclical. It'll continue to happen over time, and it may not necessarily stabilize.

An apprentice gets low pay in exchange for on-the-ground learning, and earning hours towards licensure. ...Paying ones dues, to eventually earn good income.

I'm not talking about apprentices. Most licensed journeymen (or even masters) don't own their own business or make six figures.
