Lot of folks out there hollering about trades, but I often recommend they at least get a business degree to go along with it.
But I do agree, you can't go wrong with HVAC, electrical or plumbing. They'll always been needed.
I get the what you are trying to say, but you can absolutely go wrong with those things. Everyone is is built to be in trades about as much as everyone should be a doctor. If you have a kid that is willing to bust their butt 60+ hours a week for 10-20 years in some of the most god-awful conditions you can imagine, then they are good candidates for the trades and can do very well.

@Motodawg. It ain't for many. And I know a lot more crappy HVAC, plumbing, electrical trades that live pretty crumby lives because they don't have what it takes to succeed in the field. I know when I sold my concrete business their were a bunch of kids that thought they had what it took and they lasted about as long as Clinton in Helen would with Margot Robbie.
As I have said before, there are very few people who can both master a trade and be a successful entrepreneur. Plumbing and HVAV companies have the highest failure rate of any industry in the country. Worse than startup restaurants.
Article about the challenge
A business degree may help, but being a successful entrepreneur or small business owner has a lot more to do with your willingness to be the first one in, last one to leave, and willingness to put everyone else's needs ahead of your own. You will rarely make more income than you could working for someone else for the first 5+ years and the single greatest skill you must possess is a willingness to eat shìt with a smile on your face because your customers, employees, and regulators are usually morons, but you have to have them.
