Democracy is woefully overrated and it's praise is largely because the dominant victor of WWIII said it was good so everyone had to believe it was good, but the fact of the matter is that it has only lasted ~300 years and has already deteriorated into tyranny.
Britain had ~400 years about as good as ol usa
Rome had at least 1000 years of peace comparable to the USA
And Egypt probably had ~3000 years+ of genuinely good rule for the people (hard to say it was very different than now)
