Use of Two Negatives (a Positive) Creates Confusion

Whenever I read a sentence that uses two negative terms to make a statement, I look to see if it wouldn't be clearer stated in positive terms. Here is an example from Sunday's The Birmingham News, in an article about Governor Riley's support for merit pay for teachers:

There is not another segment of society that doesn't reward its workers for a job well done.

Your brain has to do a double loop to get the meaning of this. If you flip the sentence to the positive (and leave out the unnecessary "There is," you do NOT change the meaning, but the sentence is clearer to the reader:

Every other segment of society rewards its workers for a job well done.

In defense of Governor Riley, as I've commented several times before, we all say things like this out loud because we don't have the time to proofread, but I think you will agree the "improved" version is easier to understand.
