While there are lots of examples out in the wild of people making a mess of things due to lack of experience, hastiness, and not thinking long term, there is a two way street there. Experienced developers sometimes apply too many rules and too rigidly to deliver elegant, well-performing, timely solutions. I see people abstracting and decoupling things, applying highly generalized pessimistic patterns, bickering about how to name things that probably shouldn't even exist, let alone have explicit names. Experience is obviously good but people tend to get inflexible and dogmatic, too.
