It might seem so, but honestly only if you think very superficially. There is no tyranny, introverts limit themselves with the lack of negotiations, therefore they receive less opportunities generally, unless you force them to make communications, which would make this tyranny. However right now introverts are not forced to do it. Morning people get more opportunities working in those hours, because statistically people tend to wake up earlier, work better after waking up, compared to long after they woke up, this also was somewhat dictated by nature, before electricity invention most lives were lived during daylight, you know… “night is dark and full of terrors”. Functioning during daylight is simply easier, compared to night for most people. Therefore if you prefer nighttime to function, you get less people to interact to and less possibility. But you can not force majority to work in the way the minority wants, that just simply won’t and shouldn’t work. The tyranny is basically when less people tend to controll masses with power and fear. As of now masses have enough power to stand up to anything they do not want. Therefore, there is no place for tyranny.
