I would not consider using this edict for a mere 10% increase in work productivity. Other than in the very short term, it makes sense only in a religious environment because of the negatives.
I suspect that the "Literacy Program" edict is nearly equally effective in improving productivity - albeit indirectly and with an annual cost.
Interesting that there is a five year gap in reactivating the thread.
