I think the intent here is more like “and then they shall all be equally stupid.” Removing achievement, by grades and class levels, subtly removes incentive.

You're definitely on to something here. There's an ulterior motive in there somewhere. What you suggest is part of it for sure.

The leftards approach it like it makes sense for the children, but if you have actually ran something, you understand the subtly of incentives for people. And this is directed at creating the maximum number of ignorant graduates that can easily be made into "idiot-Obama" style voters with the promise of free stuff.

Communists have done this exact thing throughout the 20th century.

Achievement is positive feedback to learning, either by actual grades, or by recognizing advancement to the next grade.
