I've got plenty of experience in trades and can do all jobs myself. It's very presumptuous of you, to think I was talking about myself but so far you've made presumptions about people in general.

Maybe you need the due diligence to realise just because you can, even with a bullshit cocky attitude, not everyone can. Some people have disabilities or learning difficulties (or both) that prevent them from "being an adult" as you so nicely put it. So instead of recognising people with these difficulties you just decide to belittle them as useless children that need us to carry them.

Here's an idea, look it up, maybe you'll learn something. What's more likely is that you'll fight doing the research because of excuses.
