Digital and design agencies generally regard branding agencies as beneath contempt. It's widely known their consumer testing sucks and is biased even by marketing standards.
The reason they get paid more, though, is because they're considered consultants that tell the board what they've already decided. Digital agencies are considered cheap expert contractors by contrast, so there's a race to the bottom in pricing.
Marketing is an evil industry that should not exist. Trust me I've been fairly high up in it.
We're in a society where the collapse of capitalism places the Bourgoisie on a single path, and so the only possible policy choice is if you whine about having to do the fascism or embrace it. So this is really the perfect example of US Political discusion.
