If you are interested in getting a Jet, be it Ducted Fan or Turbine, get one, but don't worry about what everone does for a living, it borders on intrusion; I know plenty of Jet Guys and I could care less what they do, I'm not rich, but I spend a fair bit of cash on my Scale Projects; would I like to go Jet? probably not, even if I could afford it, my desire is strictly Scale; so my advice, enjoy the sport, whatever level you decide.
