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.
Let's say you lose your job because a company lays you off without notice amid record profits. With your new found free time, you get so angry you go to your state senators and representatives and try to convince them to make a law limiting layoffs to a 6 month notice period for profitable companies. You are now a lobbyist. You are saying not to lobby the government full time. But for the sake of clarity let's say your coworkers also got laid off and pooled their money to send you to lobby on their behalf, you are now a paid lobbyist.
I feel like most people that complain about lobbyists are really just complaining about corporate lobbyists or lobbying groups paid by corporations. Lobbyists are a good and necessary part of any democracy.
