On this specific example you are right. But there once was Ashoka, who did greatly improve everything in all of India for his rule and a couple of generations ahead.

Also there was gen. Francisco Franko. Not as successful, not lasting after his rule, but still. He did greatly improve things in Spain at the time. I hope we all understand that quality of life is not just number of specifically BMWs in the yard, and freedom is not just the general election and right shit on the ruler.
