So we can agree that by absolute necessity a company needs to market its products and services due to competitors doing the same. Since, you know, you can't actually outlaw marketing, businesses have no choice to compete in this area.
Also, marketers don't work in a vacuum, they are hired by managers and business owners to create exposure and help create growth. Of course marketers work for money, we all do and very few us do work that actually help customers in a profoundly meaningful way no matter how we rationalize our work.
