I am likewise Jewish and I do think there's some cultural tendency towards observation that you're describing (hence, perhaps the over-representation of our people among both comedians and scientists) But perhaps there's a big difference between observation and griping (to use your word) - in the outcome. Observation can lead to improvement: I saw something, I called it out, and then I or someone else can fix it. Complaining to me is the non-actionable form of observation - making a lot of noise but either leading to no improvement or actually discouraging yourself and others from taking action around the topic.
