It depends.

GOod hard trades, are Electrician, Plumbing, Construction can also be good, carpentry. I would also count Coding and Accounting as hard trades, vs a soft trade like human resources etc.

Look into your localities future forecasts. My city just had a huge construction boom the past 7 years and has been pumping out traides to work construction. But now it's winding down, and there's gonna be a heap of guys losing work.

my cousin is a plumber. he's fairly well off now. Used to do a heap of coke, became religious, settled down, ran his own plubming business. Made bank.

ANy one of those hard trades can be the start to a very good future, but you have to be good at it, and have the drive to build an independent business around it. Otherwise you just wagie for someone on somewhat decent union benefits.
