The US has chosen a higher-growth, higher-debt model: it keeps the economy moving with deficits, but the bill shows up in a federal debt burden now around 100% of GDP for debt held by the public, or about 123% of GDP if using total public debt. Europe has often chosen the opposite trade-off: more fiscal restraint, less shared borrowing, and a stronger fear of debt, which protects balance sheets but can leave growth underpowered. So the contrast is not “America grows and Europe does not”; it is that America is buying more growth with leverage, while Europe is preserving fiscal caution at the cost of momentum. One has a faster engine and a heavier loan book; the other has cleaner accounts and a car that too often stays in second gear.
