Static methods act like C functions.  Sure, they are members of classes,
but in name only.  Besides, just as you can use a procedural language in
an OO fashion with enough programmer discipline, you can write in a
procedural style with an OOP language with sufficient rebellion.  Just
use one class, put everything in it and create one instance on startup.

Now that I think about it, Java is an exception to this.  There are per
class code and variable limits in the JVM, limiting the size of your
procedural program masquerading as a class.  Perhaps that is a good
thing.
