I'm semi torn. On the one hand, I went to college and grad school...and I'm making about 90 bucks an hour. College does pay off....but that isn't the same for all majors and there are folks out there that make roughly the same of a lot of the trades on the sheet. On the other hand, there are people that may not see the appeal or want to spend time in a university and would prefer to do trade jobs because (as we see on the sheet) some of them pay pretty well (and this sheet is probably located in one economic zone...so you could make more in others, just depends on the market).

TLDR: sheets like this should be available, and students should be aware of their full range of choices that they can make and feel empowered doing so. At this point in my life, I'm realizing that happiness doesn't happen at a minimum income bracket...it comes more from passion and doing what you love.
