Are there any occupations you uniquely oppose the existence of?
I did retirement home training and used to think it was a sweet job. Then I got in the business and underestimated how demoralizing it was as they give you the easy elders in training while the others make you, or at least me, really think of the fact the job just amounts to an unkarmic freebie.
What about a lobbyist who works for say the Electronic Frontier Foundation? Or a nurses union. Or who works for the Sierra Club, or some organization trying to protect the environment?
"Lobbying" is just talking to a politician on behalf of a person or group. If the Hollywood studios all hire lobbyists to talk to representatives about why copyright terms should be longer and DRM should be mandatory, doesn't it make sense that there should be people telling the other side?
I get that too often lobbyists overstep ethical boundaries. Often, they either effectively bribe politicians, or they write up laws allowing the politician to just rubber-stamp them. But, you could shore up and/or enforce laws restricting that kind of thing, while still allowing a representative of a group to meet with a politician and explain their point of view.
