I do find some people who are absolutely terrible online too and claim that they are professional designers though! So, a lot of pro designers would be right in thinking that, because you can pretty much tell straight away who knows the rules of good design and who doesn't. They might be excellent at illustration, but their ability to actually design is blah. Crowdsourcing sites like 99designs are full of them which is why I don't waste my time on it. The client is not getting what they need. They are getting what they want, visually, at that particular time, but they aren't getting something that is created to the specific needs of their company. It's so, uh... dishonest? Yeah, I think that's the word for it. Also, you have a bunch of newly qualified designers working for free in the hopes that they get paid. All them wasted hours.
I feel that both the designer and the client are being exploited in those instances. The prettiest might not actually be the best solution. Like some of the most successful brand identities in the world are the simplest. They're immediately recognisable and memorable.
You can be right about some designers though. I do know one guy that was in my Master's class last year and he wasn't a good designer at all, yet, he thought he was. It wasn't until he accepted his flaws that his stuff improved immensely.
