Okay... I am going to offer my ?2, even if I am not a parent, nor am I sure whether I want to have kids, but as someone who grew up in an affluent area of OC. And, it is not personally directed at anyone here, but it is just my own personal experience of growing up in an affluent area of OC.
I think you will find the materialistic side of OC no matter where in OC you raise your kids. Will the ratio of that influence be higher in Newport than OC? Maybe, but as a parent it is up to you help influence this, and if the outside factors change that influence, then there is nothing you can do. Where I grew up, some of my friends and myself thought the LV bag came standard with the Mercedes that some of the moms drove. Why? Because my mom and my friends' moms didn't drive Mercedes or have a LV bag. Hell, you can see this in Anaheim just as you can see it in Coto. This influence is everywhere in OC.
I was lucky I learned from my dad at a young age that it wasn't the material things that brought you wealth, it was the timing of buying assets. He made his mistakes, and was not ashamed of hiding them from me to teach me a lesson. He knew this housing bubble was starting in 2002, when we were looking for cash flow positive investment properties, and we couldn't find any. I was still very green in the RE business, and I bought into the bubble without knowing it. My dad let me buy into it, and made a great decision too, and now I am seeing the lesson he was trying to teach me. Sometimes you need to learn a lesson the hard way, and I am doing that. But, if he were here today, he would know that I have learned a valuable lesson and I am taking what I have learned to use for my own advantage. I am also proving him wrong that if you take care of a bimmer, then the bimmer will take care of you too. He would be proud to see both of those lessons learned, his and mine.
Anyway, my point is the influence of materialism will be anywhere in OC from Anaheim to Coto to Newport to VP, they all have the spoiled brats with mommy or daddy taking care of everything. Some will turn out great, and take over the family business, and some will be living at home with their illegitimate child, working at Office Depot, and stuck having to ask for rides outside of work because they have four DUIs. Some will see their parents go from riches to rags, and still do the same dumb thing their parents did, not once but multiple times. All you can do as a parent is try to teach them that is not the life to expect, and if they end up being influenced by that, then you have to remember they are people too, with their own minds that can make their own decisions. All you can do is try your best to be the stronger influence than the outside influences. Which is easier said than done.
One last thing, I just hung out with a family who had three kids that are now all adults. They raised them in pretty much the same way, and now two are very successful, but one is still stuck in the entitlement stage. So, consider that as one in three will be influenced no matter what you do, and despite the results of the others. That is the risk you take by having kids, and a risk that I highly consider, because I know I can and will do my best to be the best parent as possible, but there are some things I just cannot control.
All in all, live in the place that you love. I like Coto, but I would much rather be closer to the beach than that. Will my opinion change if when I decide if I ever want kids? Sure, but I still will want to live where I love, and that could be north Tustin or even Orchard Hills. We will see what happens as this bubble creates opportunity for those who learn from others.
