@boomerang,
The GED has been a godsend for many. There are a lot of people who for a number of reasons are not able to finish high school and thus gain their diploma. For some it is a matter of things happening at home (sick parent who needs help tending younger siblings), for some the inability to assimilate into regular school life (there can be many reasons, including bullying from others and learning handicaps). In some places, the standards for the high school diploma is far beyond what a GED requires. In some places, taking a foreign language course is part of the requirement to gain a diploma, science and math courses which are at a level higher than a GED would currently ask for.
With a GED, the person is better equipped at facing life, getting a job and perhaps even then eyeing a college education or a trade school education (some form of advanced education).
I grew up knowing people who decide on a GED for many reasons. The same happened with students I had the challenge of teaching. There are young people who have ADD and others with dyslexia and some with both. They aren't lacking the intelligence needed for the courses taught in high school; however, they are not able to mesh in with regular school formats. A GED gives them the opportunity to move forward.
From Walter who was unable to learn under normal educational restrictions, to Renee who had to leave school because of circumstances at home, there have been examples of people who became successful and even obtained degrees from colleges because they were able to take the GED route.
I'd not want to think of this form of opportunity being eliminated.
