One of thing that is obvious to me is the bizarre cultural norm that, in the US, people are expected to move away from home at the age of 18 and then relocate more-or-less permanently far away from family and childhood friends.<p>To my American friends this seems totally normal, and suggesting something different is ridiculed.<p>An obvious consequence of this is that American adults have 3 or 4 "social fabric ruptures" as they grow up:<p>1. When they turn 18 they move far from home to go to college temporarily. They develop a new group of friends, at the expense of being far from family & home.<p>2. When they turn 22 they move to Big City for a job. Probably _not_ where their parents live, and almost certainly not where their college friends live.<p>3. There's another (optional) move to Different Big City in late 20s<p>4. Finally they marry and in their early 30s they move to Suburb (leaving their Big City friends behind).<p>The result of this is an absolutely frayed social fabric. Not only do people leave their friends behind <i>just</i> as they start to develop deep friendships, they do so in an environment where building <i>new</i> friendships is harder (because they keep getting older).<p>If one wanted to design a system that maximized unhappiness, it would be pretty close to this! <i>Of course</i> Americans are lonely! They keep leaving their family and friends behind!<p>There's two reasons for this, imho.<p>Firstly, the cultural norm of "the real college experience" requiring dorms, facilities, football stadiums, etc. Being a commuter student in the USA is weird at best at most colleges, and certainly the good ones.<p>Secondly (and perhaps most importantly), is a set of policies (transit, zoning) that make the places where old people/families want to live different from the places young people want to live. This results in the 30-something move to the suburbs, but it also results in the 18-something move to the city or ~disneyland~ college campus: <i>of course</i> you don't want to be a commuter student if your parents live in the suburbs: there's nothing to do! You can't drink, you can't party, you can't <i>do</i> anything.<p>This social norm has a whole other series of consequences besides just loneliness. Financially:<p>- It's inefficient at best and ruinous at worst: Not only is sleep-away college expensive, it also creates a rat race between schools for bigger/better facilities resulting in runaway costs.<p>- Young adults entering the workforce don't live at home, which means they don't create a savings cushion to help them buy their first home in their late 20s (compounded with college debt due to the point above)<p>- Families with kids often end up far from grandparents/family/trusted friends, further increasing the financial "overhead" of just <i>living</i>.
