Lots of people had good answers so I want to point out something you touched on that was very observant and extremely true and hasn't been mentioned elsewhere here.

Automatically creating setters and getters is a horrible, horrible idea, yet it's the first way procedural-minded people try to force OO into their mindset. Setters and getters, along with properties should only be created when you find you need them and not everyby default

In fact although you need getters pretty regularly, the only way setters or writable properties should ever exist in your code is through a builder pattern where they are locked down after the object has been completely instantiated.

Many classes are mutable after creation which is fine, it just shouldn't have it's properties directly manipulated--instead it should be asked to manipulate it's properties through method calls with actual business logic in them (Yes, a setter is pretty much the same thing as directly manipulating the property)

Now this doesn't really apply to "Scripting" style code/languages either but to code you create for someone else and expect others to read repeatedly over the years. I've had to start making that distinction lately because I enjoy messing with Groovy so much and there is a huge difference in targets.
