You'll find bad professionals everywhere you'll look. The difference is that a marketers job is more visible then a devs, because most of it is to get in front of people's eyes balls.

That's why it's easy to perceive that marketing is mostly shit... because it is, and no wonder, it's not "hidden" in the backend or in some git repo.

Ads live in public scrutiny.

A lot of the dev work would probably just make you cringe just like many ads. You just don't see it.

With that said, you're right that the barrier of entry it's lower, and I don't think the hard part of marketing/advertising is the campaign setups - that's mostly being reduced to a step-by-step wizard. Thankfully! But that won't make marketing any good, in fact, you'll just see more of the bad stuff.

It's less about transparency and more about the culture. Developers sell deliverables and marketing consultants sell attempts. As the GP said very few are actually willing to charge based on conversions, because they know they won't make many. Smoke and mirrors.
