In many cases, everything is public is the wrong default.  For an example, take a look at the XML coffee cup.  Look at all the overhead the wrong default causes in this example.  Not to mention all the parenthesis.

If you want a good example of a lot of overhead, select "view->source" in the browser while you are on this page.
