That's a strange point of view, I would love to see a good example of
that.  If you've got a system designed that way, then you've got bigger
problems.  IMO, tight coupling is the best way to complicate things, not
the other way around.  The point is, the default position should be to
loosely couple your code unless you have good reason to do otherwise.
The default position should not be to tightly couple your classes unless
you see a reason to do otherwise.
