Are suburban families happy? Is that really a goal we should strive for?

Im 25 and live in the U.S., a lot of my friends are starting to get married, start families and move to cookie-cutter houses in the suburbs. Growing up we were always taught to strive to meet someone, get married before 30 and live in a quiet neighborhood with neighbors just like us. However Im starting to see the reality of this situation. Husbands arent happy, wives arent happy, kids feel the brunt of it all. I grew up in the suburbs, so maybe I am projecting from my own experience, but most families I had seen were miserable!! Any insight ??
