It really depends what "few" means.
A benevolent dictator would do a nationwide cost-benefit analysis, and decide if 30 families having no sleep for a week outweighs 100,000 people getting to work 10 minutes faster for the next decade.
While sometimes our existing legal system makes the same choice as our fictional benevolent dictator, sometimes it doesn't because rather than looking at the big picture, it gets tied up with nuances of wording of ordinances and precident written decades earlier without knowledge of the current situation.
Whenever that happens, on average, people's lives get worse and the economy weaker, compared to an identical country which made the benevolent dictator choice.
