The American consumer market is larger than the EU and China's combined

X items per 100k then normalize #s for population. Or actual consumptions of atoms, i.e. electricity, metals, resources.

Depends on what you want to measure, real economic activity or spreadsheet value. Nominal good rough indicator, but countries calculate consumption differently, i.e. PRC lowballs imputed rent, doesn't include social transfers in kind (basically gov expenditure that US bundles into private / household spending). Same with EU welfare state math. These numbers aren't derived from same formula (US formula distorts up).

There's also considerations like value vs extraction... i.e. huge % of US consumption is high rent health care and education. PRC generates magnitude more tertiary with fraction of education spending, we don't say they consume less education. Or American spends 40k on tertiary + healthcare vs Europoor spending 10k. US simply overpaying vs others good for nominal but not actual consumption #s. Or US healthcare spend is ~8% higher than OCED average for comparable / worse outcomes. That's ~2T per year right there, for reference entire PRC HSR network is 1T.

Now spreadsheet $$$ is also "real" in the sense it buys stuff / certain advantages / capture market demand, but it can't buy everything... i.e. a PRC industrial base. On paper it should, but in reality having massive $$$ circulating due to overly extractive consumer economy encourages other easy extractive (service) business models. Service dutch disease. So higher nominal = both strategic and detrimental. Hyper optimized for quarterly profits at expense of overall political economy.
