Also valid but the incentive structure simply does not cater to those benefits being consistent or unabused for long. Years, decades they'll last, but not forever. Eventually snakes will get into the garden.

In some countries unions tell the government what the conditions are and if they don’t comply with the demands the stop producing, eventually the government gives in because they can’t afford to piss so any people off, these regulations have been around for 50 years or more
I'm sure that is the case in most places but the same can be accomplished via general unity and without compulsory dues. I don't mean to sound pessimistic, maybe there isn't an organization I'm not cynical about. If our governments actually worked for our best interest maybe that would change.
