|---|---|---|
| United States | $186.3 billion | US Dollars |
| United Kingdom | £23.5 billion | Pounds Sterling |
| France | 2,400 billion francs | French Francs |
| Germany | 120 billion marks | Gold Marks |
US already largest national economy (overtook UK ~1870s). Wealth concentration extreme: top 1% held 40-50% in US/UK. War would shatter these valuations—inflation, destruction, debt, revolution.
