If you took the REAL percentage of porn models who have been abused and the REAL percentage of non-porn-models who have been abused (you'd need a consistent definition of what "abused" is), I suspect that you'd find that the abuse gap is not as large as you think, ie I suspect that models are more likely to have been abused, but your estimate of 80% is too high and your implied (presumably much lower) estimate for the general population is too low
