Not joking and I agree 100% that LDS and instructors make very little money and I don't really understand why you all do it. However my point was regarding stupid lawsuits and personal responsibility.
I can't speak for others. I do this on the side (well, I did before having a baby due in November and this film project in Greece, but I'll start up again). Long term, I plan on opening up a dive op in Greece where the cost of living is much, much lower. Hours each day will be longer, but not as stressful as working in tech (though current job I just started is AWESOME!). I just want to live the Greek island lifestyle and a dive op is the only practical way to achieve that.
I used to be a ski patroller (on weekends). Skiing became a tax deduction (miles, equipment, dues). Some days on the mountain really sucked. My red jacket had some nasty oil stains from adjusting tower pads on wet days.
But then some of my best days, my best actually, were when patrolling. My best day was on president's day, sunny, but with a thin layer of clouds, so the snow softened, becoming the most forgiving I've ever experienced. No accidents, so we took turns skiing our asses off. Because we were patrollers, we never waited in line.
I suspect that some do this on the side, taking peanuts, as it gets them to get out there. Plus some enjoy teaching.
I know a number of instructors in my local area who will only teach at max ratio with everyone on their knees, as it isn't "worth my time" (their words) otherwise. Well, even the extra money from the extra students is nothing compared to their primary job. I don't understand why they do it. Why not focus on getting better results with smaller ratios? The difference in pay in the grand scheme of things is insignificant. Teach well and people will come to you when you are independent. I taught for shops just to cut my teeth. Now I get referrals from former students and more importantly, people who dive with my former students.
