Public wealth is the kind that makes you happy

By the metric currently in fashion which is how much stuff everybody has, the United States is the most successful country in human history.

That metric is only measuring one of the two kinds of wealth and the distinction explains a lot of what looks like a paradox from outside. Private wealth is what you own. The money in your account, the car on the drive, the house you live in, the things inside it and public wealth is what you share with everyone else and how good it is. The state of the roads and the trains. How easy it is to see a doctor. Whether public space is pleasant and whether it’s safe. How you feel when you’re not at home.

On private wealth, Americans do extraordinarily well, especially measured against anywhere else and on public wealth the country ranks a long way down.

The awkward part is that it’s public wealth that actually makes people happy, unless you’re rich enough to avoid shared space entirely which is a fraction of a fraction of the population and not a fraction anybody should be designing a society around.

You can see why once you look at how the two interact and owning a luxury car while the roads are terrible isn’t a luxury experience. It’s a daily reminder that your money can’t solve the problem you’re currently sitting in. Being able to afford the best restaurant in the city doesn’t help much if you’re nervous waiting outside for a cab afterwards and the meal doesn’t get better retrospectively because the wine was excellent.

That pattern holds across most of life. Private wealth buys you things. Public wealth determines what it’s like to be a person moving through a day and no amount of the first one buys you out of the second unless you can go from a gated house to a private car to a private terminal and never touch anything shared.

Which is the thing worth noticing about how wealth gets measured and argued about. Almost every comparison between countries is a comparison of the private kind because it’s easy to count and it fits in a chart. The other kind shows up as a feeling and feelings get treated as soft, and so the number that gets optimised is the one that turns out not to be the one people are experiencing.

Society has to feel safe before anybody can be properly happy inside it. That’s not a political claim so much as an observation about where most of your waking life happens which is outside your house, in places you don’t own and can’t improve on your own.

The practical version of this is what happens to a country over decades when it consistently trades one for the other. Every individual decision to spend less on shared things and leave the money with people to spend privately looks reasonable in isolation, and it hands you back a portion of what was being spent on your behalf, and you can point at exactly what you bought with it.

What you can’t point at is the thing that quietly stopped working, because nobody experiences the absence of a decent train service as a purchase they made. It arrives as a background sense that everything is slightly harder than it used to be, and there’s nothing to attribute it to.

It also explains why moving somewhere poorer can feel like an upgrade, which surprises people who only think in the private column. Take a smaller salary in a place with decent transport, walkable streets and healthcare you don’t have to think about, and the spreadsheet says you’ve gone backwards while the daily experience says otherwise. Both are true. They’re measuring different things, and only one of them is what you live in.
