Okay, let's take an excerpt from one of those enterprise "hello world"s:

    IHelloWorldString helloWorldString = helloWorld.getHelloWorld();
    IPrintStrategy printStrategy = helloWorld.getPrintStrategy();
    IStatusCode code = helloWorld.print(printStrategy, helloWorldString);

Extracting two subobjects from an object to feed them back to the same very object is not an abstraction, it's merely adding a bunch of public methods (and interfaces) to the object. That may or may not help in abstracting things: and usually, the more handles and bells and whistles are available to pull and play with, the less abstracted the code actually is.
