What no one here has mentioned- and I don’t know why- is that in LA in general and specifically in the Frum community in LA there is an extreme open-mindedness that is not healthy. Like some people I know like to say- they’re so open-minded their brains fell out. There is very little hadrachah from the Rabbanim and very little hadrachah on a more personal level within the family unit. Everyone needs to be accepting and open-minded to everything they encounter, which leads to confusion, people having all sorts of warped values and a dearth of true Torah hashkafah. Secondly, and perhaps more importantly, there is an enfatuation in LA, not just the frum community in LA, with gashmiyus. Specifically that life is all about how geshmak and easy someone has it (the weather is so nice! and therefore it’s the greatest place in the world….?). There is a lack of stress and focus on accomplishing, achieving and doing, like there is in other big Frum areas.
For someone who is living life to break-away from and disassociate as much as he can with a corporeal and materialistic existence I would think that living in Los Angeles would be a tremendous impediment.
