The problem is two fold tho.
Problem 1) To get work they have forced any writers to be part of their union or be shunned. This is a fundamentally flawed system as it gives them absolute power and prevents other people from having different opinions. This is essentially a monopoly on the workforce.
Problem 2) Since you are either part of the guild or you're not a working writer you have to be part of the guild to be a writer. And then even when you disagree with their choices you are forced to go along with it.
There has to be some way for a minority to exist. This is a frighteningly controlled system and in my opinion is a gross abuse of power.
