There's a famous bit of research done by the guy who wrote Freakonomics.
He tracked how much drug dealers were actually making and found that if they just got a job at McDonald's they'd have a higher income.

I can't speak for a larger group, of course. Perhaps the average is weighed down by more casual actors.
The issue of tax fraud is only an issue if they investigate you - someone in the tax department would have to find a reason to take notice. In the case of a narcotics trafficker it's more likely that activity would be observed by drug investigators than for the tax department would determine there's someone paying a mortgage or rent that isn't a significant income tax payer. That's not really how tax investigations work.
They turned me down.
