Private vs. Public members in practice (how important is encapsulation?) [closed]

Answer 1

I base my decision on the Code's depth within a module. If I'm writting code that is internal to a module, and does not interface with the outside world I don't encapsulate things with private as much because it affects my programmer performance (how fast I can write and rewrite my code).

But for the objects that server as the module's interface with user code, then I adhere to strict privacy patterns.
