It's weird, I wouldn't have imagined those two to be hugely different when it comes to to things like human development or corruption, but in on this map, they're on opposite ends of the spectrum, Bulgaria being the lowest value bar none, and Romania being surprised only by Austria...
One thing I like about Romania is that it seems to be steadily improving the last 30 years or so. Granted, it had a terrible starting point, and improvements are slow as hell, but whenever I check up on them things never seem to be actively getting much worse.
My guess is they're that much closer, geographically and chronologically, to what real authoritarian hell actually looks like. So, they have some actual perspective.
