Maybe, maybe not. This is speculation, unless you've done a study to sample a statistically significant portion of the population. I agree, your speculation sounds reasonable. But neither of us knows, and both of us have certain biases that this speculation confirms - and therefore it should be mistrusted until confirmed.

Frankly, I think there is a bigger problem than job security itself. It's that the whistle will be ignored by the general population. Even if you are willing to sacrifice to do what is right, it may not matter because no-one wants to believe, or the spin is so good that no-one believes it anyway.
