It's about the same in the US, where being in the trades isn't exactly widely and highly regarded, but it will get you a middle-class lifestyle. The difference is that for the most part it's a lot harder work than an office job with an equivalent pay; you don't get paid if you don't work, you will have to work in 120ºF attics in the middle of the summer, and it will leave a toll on your body after decades.
