Well, I think it's far to strong a statement to say there is "no" reason to declare fields in a sub class public. In fact it's done all the time in the Java API.

What you should say is that you don't see how sub-classing will implement the solution you were hoping for (whatever solution that might be). That's fine. Sub-classing and inheritance is not a panacea in OOD. In fact, you should avoid it and favor composition and concrete classes if possible.

Inheritance is kind of a last resort solution, and getting it correct can be tricky, as you are discovering.
