Gross production is sales $$$, it's not actual output of widgets. I imagine if measure gross production by some units of stuff made, PRC would be far ahead.
Yes, but $$$ is the currently the most accurate metric of "units of stuff" by their usefulness. At least there's no other widely used metric. So $$$ is the most correct way to measure the output.
I think it's just the simplest (also default*) way of measuring, which doesn't mean it most correct or accurate. If PRC makes 5 cars @10k for every 1 US car @50k , and each PRC car is 80% as good, which metric do you use to measure gross manufacturing. Most people would say the guy that makes 5 cars. They might say the guy that makes 1 car if the 5 car guy's cars were 10% as good. What if its 3 cars that is just as good as 1 car charged at 3x. Across the board you have made in America stuff that's a little to a lot better (or worse) than PRC stuff, but cost 2-5x more.
* by default I mean, these metrics/calculations are downstream of national accounting methods, i.e. most of world standardized on UN SNA which measures "value" as in $$$ vs something like (deprecated) soviet material production system (MPS) that measures physical material widgets produced.
One proxy metric is PRC container throughput of her ports last year was ~300 million TEU vs US is about ~60 million TEU (with slightly higher ratio of empty containers).
The price (that consumers are willing to pay) is the only decent proxy for quality we have. Quality, of course, includes consumers’ preferences.
If the one car sells at a market price of 1/5 of another, then the only reasonable conclusion is that, as judged by consumers, one car is worth 5x as much as the other, and therefore is 5x better.
That’s what market prices are: the collective valuation of goods/services and their alternatives. Of course, the market clears at a price that is a combination (you can think of “average”, but that arithmetic is not the process by which prices are discovered) of the preferences of all consumers in the market.
If you have a preference that goes counter to the market, e.g., if you do not think those two cars are 5x different in quality, then there is a great deal for you!
If you think the worse car is only 2/5 the quality (rather than 1/5), then you can get something for half the price you’d be willing to pay if the rest of the market agreed with your preference.
If, on the other hand, you think the better car is 10x the quality of the worse car, then the same “deal” is true for you. You’d be willing to pay 10x the cost, but you only have to pay 5x the cost.
There are plenty of good macro and micro econ courses available for free if you’d like to dig into this sort of thing more.
If that was true USA would export its industry produces, but the rest of the world mostly don't want what USA makes, meaning it isn't actually worth that much.
Some don't, but many do. Does a 600k NVIDIA AI rack provide as much value as 600k worth of commodity solar panels, or 10,000 entry level mopeds? Most of the world (developing) benefits more from commodity widgets.
