Let’s all look at this from its broader perspective. Hashem has two basic modes of coducting the world: 1) When His presence is obvious, such as in the days of the Bais haMkdash, when there were daily miracles. 2) When his presence isn’t obvious.
Corresponding to that, He engineered two modes of society 1) when people find Him on their own 2) when society holds each other to a basic level of commitment.
Only the second society can be on the level that merits His revelation. The first, however, affords the indiidual the oportunity for making it on his own.
We have only seen the first type of society, so we cannot judge what the second looks like.
