Neither am I, I just play one in real life.
Believe it or not, engineers don't make that much money. It's about the same as any other profession. And I get shafted on my salary every year so that doesn't help either.

I guess it also depends on how busy your life style is and what your hobbies are. I used to love designing little gadgets in my spare time but when you're doing it 10 hrs a day, all you wanna do when you get home is anything else.
