Undervaluing "quality" jobs or naive parents?

Although I am more concerned with higher education, I found a somewhat interesting but more entertaining article on the Gallup site titled, U.S. Parents Optimistic About Graduation, Unsure About Jobs.  When you read this, or at least when I read this, I figured they would be talking about graduating from college, but they are actaully talking about graduating from HIGH SCHOOL.  In the main poll of this...poll... they ask people to rate on a 1-5 scale whether they know their child will graduate from high school and whether they know they will find a good job.  An overwhelming 91% of parents strongly agreed that they knew their child would graduate from high school (although the national average is only 73%) whereas 38% strongly agreed their child would find a good job after graduation.  Oddly enough, before dipping down into the 1's and 2's of this response (being that they disagree about the respective questions) 89% answered either 5-4-3 (saying they at least agreed) that they knew their child would find a good job after high school.  So does this poll eliminate the children planning on going to college? or are these respondent's children just not going to college?  And if they are not planning on going to college but are going to find a good job out of high school, why are the parents so eager to say that they KNOW they will graduate from high school (which 99% answered a 5-4-3 on).  This is obviously a poll with horrible questioning and problems with "mushiness index" because the question is too close to home (literally) for the respondents.
