To be fair, if you pay attention, the overblown evolution levels correlate with their locations in the region (which partially correlate with their position in the dex). Starters and early route mons have very normal evolution levels, while shit hits the fan as you approach the later gyms.
I get what they were trying to do - you're most likely going to see first Mienfoo around its late thirties, and they didn't want you to evolve it straight away without getting familiar with it. But they failed to calibrate the whole thing. Which would become an problem if/when they wanted to add those mons in earlier routes for future games (Rufflet/Vullaby appear in Route 3 in Alola for example, and if you started SV after getting the DLC, you can head to Kitakami and catch Mienfoo straight after starting the treasure hunt)
The fact they tried to fix it a bit in B2W2 by adding a few underleveled static encounters shows they know they fucked up.
