In our world today, I strongly believe graphics designers deserve more, because we are the brain behind brands, client needs to understand this job is not a easy one, The pay is too small also, Am a professional graphics designer, my experience has tought me not settle for less, Graphics designers all over the world needs to stop accepting poor payment just because they are looking for job.
Note: This post is what I feel not to cause misunderstanding on the forum, Thanks.
Depends on what you mean by "poor payment". If by that you mean lower payments, I'll assure you that's how to be competitive. If the graphic designers form a union to impose your idea, the food sellers who will probably need their services could also gang up to increase the prices of food in to be able to afford your services and possibly other services that discourages such competitive behavior... Food will become expensive and you will be tempted to increase your price again to be able to feed properly and survive.
