> At the time GDP of the Eurozone was comparable to the US' now the US is almost twice as big

No, You're just comparing change in the EUR/USD exchange rate here. In 2007, the euro was at a high point of 1.48, and in 2024 it's at a low of 1.02. Inflation has not been higher in Europe than in the USA over that period.

If we look at GDP at purchasing power parity from 2007 to 2023 we have this:

- European Union: 31,162 → 61,217, +96% (https://data.worldbank.org/indicator/NY.GDP.PCAP.PP.CD?locat...)

- USA: 48,050 → 82,769, +72% (https://data.worldbank.org/indicator/NY.GDP.PCAP.PP.CD?locat...)

Which shows a slight catching-up by the European Union over the period.

The US are leaving Europe behind in term of growth (and thus ultimately GDP and GDP per capita) in any case [1] [2].

"Between 2010 and 2023, the cumulative growth rate of GDP reached 34% in the United States, compared with just 21% in the European Union and 18% in the eurozone. This measure of GDP in volume does not depend on changes in exchange rates." [2]
