Boeing actually benefits from keeping training low, it's actually a barrier to entry for competing planes. Boeing is appealing to airlines that have a lot of Boeing pilots because of the low retraining when upgrading models, this allows Boeing to overcharge those airlines since they can make a margin on the retraining costs the company would otherwise need to put out. From what I can tell (IANAP) the MAX was specifically designed to maximize this margin by the promise of that hour, possibly this grounding wouldn't have happened if Boeing had stated a slightly higher retraining requirement, and possibly a PHB overrode a suggestion from an engineer for some extra training time to maximize that window. That's all speculation, but it'd be extremely unsurprising.
