Can you elaborate?
Sure. Probably the clearest example applies directly to the Weinstein case. Hollywood is a really extreme version of the problem than most places for a few reasos - the money, the endless stream of ambitious people willing to give anything to become famous, the way getting a break is as much about connections and luck as anything more objective. But I also think a real factor is that for many actors performing sexually is already part of their job description. Everyone is used to the idea that sex is a commodity, and those who want roles are more likely to get them if they are willing to accept that. It isn't that much of a step to go farther and see sex off-screen as another part of the job.
I think to fix this there really needs to be a rethinking of sexual content in films and television, because frankly it's a workplace. People need to become re-sensitised to the fact that it is a person in a job on the screen, and concern about that is not prudishness. I don't think we are really willing to do that on a cultural level though, despite the stuff I've seen recently about "intimacy coordinators."
More generally, I don't think people have been very willing to talk about how we draw lines in the workplace, in part because I think there are significant differences of opinion. But unless we have general agreement, or at least everyone is working from the same playbook even if they don't like it, acceptable standards will remain unclear and that leaves gaps that can be exploited by the unprincipled.
For example, I've talked to people who want to ban all relationships of any kind in workplaces, as leading to problems. Others think that is a bad idea, it will drive them underground because it goes against human nature, people will form relationships with people they interact with regularly, and that will cause worse problems. Others object because they see it as the workplace intruding into people's private lives in an unacceptable way. All of which are reasonable points, but I can't say I've seen much appetite to really tackle them. Maybe there isn't much of a starting place to do so.
If it were a more limited goal, I think there would be a better chance, but once Metoo opened up into accounts of like the Ansari story, that possibility kind of evaporated.
