Monkey, aviation is an addiction. It takes all your money, forces you to make foolish decisions, thus ruining your life. Ask me how I know...
If you really want some answers, I can only give you the American perspective; don't know much about the industry over there.
1. You can't make money instructing. Period.
2. It's fairly easy to work up to a twin-turboprop job, either in cargo or medivac. All you have to do is be able to live on sub-poverty wages for 3 years or so. Once you get the t-prop job, you'll be making $50K/year, ie middle class. And that's as far as you'll ever go, unless you're willing to take a regional airline job, and return to the sub-poverty wage for another 10 years or so.
