> pornography is an industry rife with problems of trafficking, abuse, etc.
In my experience in the industry that is perception, not reality. There were a few cases to make the news cycle, like the Girls Do Porn lawsuit and the MindGeek/PornHub controversy with user-submitted content.
But precisely because of public perception the adult industry tends to be pretty good at self-regulating in my experience and opinion. I remember getting an email from a sponsor of mine several years ago telling us that their content could in no way be associated with text that includes "drunk / drinking / intoxicated" etc. and they told us that we had to change the copy on the pages that featured their content. Consent is a huge topic and way more nuanced than most people assume.
The finance industry on the other hand? We're talking about institutions that fund weapons dealers and warlords. With global investments from rights-infringing countries. Not to mention the white collar crime and corruption that comes out of that industry.
Public perception of the adult industry being "rife with problems" stems from the taboo and ideology IMO. Nothing is without problems, but it's all relative and some industries do have it worse than others.
