@Hi My Name Is,
We're drawing some mighty-large associations here
[INDENT]1. High grades does not correlate to how productive, 'good, or successful one is in any context.
2. Low or high grades in school measures how well someone's assimilated the knowledge and concepts presented; nothing more, nothing less
3. Grading doesn't even accurately represent this very well either. Other factors disconnect the "how well" from the grade received (everything from test formulation to test anxiety to what Billy had for breakfast to how many others were in the class and on and on).
4. The worst false-correlation I see, is the implied "worth" given to the people graded; as if this had anything to do with success in life, industry, community, etc. The longer you stick around the more, I believe, you'll find that this is no correlation at all.
5. I also see an implication that perhaps more effort (or resources) might be available to invest into <this set of students> or <that>. I fear that for those of elementary, junior or high school; school is just a way of "babysitting". My country hasn't any concept of the importance of quality education - so it's constantly cut/marginalized while parents just want junior out of their hair. Apologies for the negativity here, this is just a trend I'm seeing.
