One issue with porn is that it's one of the few professions that allows someone to live an unhealthy lifestyle while still making decent money.

So porn can end up being an enabler that allows already troubled girls to continue living that lifestyle - ie getting high, sleeping in all day, and otherwise living a "NEET" lifestyle while never having to change their way of life.

Then they "age" out of the industry and now they're 27, still addicted to meth or cocaine or etc with no job experience or the social skills needed to keep a traditional job, and their life is basically a mess.

Of course there's nothing saying you can't use porn to pay your way through college or start your own business, which is the smart thing to do. But it often doesn't happen that way.
