Reality is fucking far away from averages and we know it. "The economy is doing great/terrible" is an almost worthless indicator unless the person you're talking about actually has business relations into every corner.
Yes, there are interdependencies, but they do not justify that we pretend numbers are so expensive we can only print two of them (mean, sd) at a time. Let's finally stop drinking information through a 2 mile straw and instead show high resolution 2d data at least.
[edit] this is of course not a criticism of parent or OP, it's a systemic problem that we all are guilty of.
