This reminds me of a story about a French ship that landed someplace, and a native of the area walked down the beach and greeted them, saying “Bonjour.” Shocked that the locals spoke perfect French, the sailors asked “Parlez-vous francais??” and the local, confusedly asked “what did you say?” in the local language.
As it turns out, both the local language and French had apparently arrived at more or less the exact same word for a greeting by pure coincidence.
I see, so you understand that an economy exists, but not that it has many different interlocking pieces that can be examined in different ways. Let me see if I can break it down for you:
When you spend money at the store, when the store pays its employees, or when it buys goods from other vendors, are all examples of what is often referred to as “economic activity”. This can take many different forms at many different scales, in much the same way that a walk around the block is not considered an international flight.
For example, you go to the store and purchase a head of lettuce to make a salad. The store buys that lettuce from a local vendor who gets it from a local farm. That entire chain of transactions would be considered part of the “local economy”.
The fact that the US buys more than half of its aluminum from Canada would be considered “international economics” as the transactions involved take place between two different countries. In this way, you can examine different economics from as small a scale as you buying eggs from your neighbor who has chickens to the macro-economics of multinational corporations dictating the stupid price of RAM by effectively buying goods that don’t exist with money that doesn’t exist while handing the same 20 dollars back and forth to inflate their stock value to a disgusting degree. Hell, you can even pick out specific sectors, like with the aluminum example: when Trump started his pissing contest with Canada with tariffs, the American car manufacturing industry said that tariffs on aluminum would cause them to shut down plants within 6 weeks.
So when we talk about the economy of California, people are talking about the farms, the restaurants, the businesses that exist in the state. The people who work and live there, and the money that flows between them all. If these companies were to pull out of California, they’d be leaving all of that behind. Even ignoring the idea of the loss of sales, they’d also be losing the experience and skill of the people that they employ in the state, and the “value” of the property that they have there - whether that’s real estate or more logistics based like renting storage for goods or the cost of transportation from a manufacturing facility in a new location.
What economy is exclusive to the United States?
People and businesses located in California buy goods and services, and produce goods and services that are sold both in the local region and abroad. This exchange of goods and services is frequently called an “economy”.
The economic activity within the state of California would make it the 4th largest economy in the world if it were an independent country, and it is the largest subregional economy in the world.
That’s so much cooler than the plastic shell that you could put your phone in that Bethesda sold with one of the games for like $200.
I remember reading about a group of researchers many years ago who had developed a subdermal LED screen that could be implanted and ran off of the oxygen in your blood stream via a tiny turbine or something.
Don’t forget the number of places named Springfield. A quick search pulls up an article that puts the number at at least 30 different places in the US.
