That's false. France has a higher cost of living and higher food prices [1], with a considerably lower overall median and full-time median income level, versus the US. US GDP per capita is also currently 50% higher than France. France has an unemployment rate ~120% higher than in the US. US wage growth has been roughly 8x to 10x that of France over the last 20 years (France only averaged 0.5% annual wage growth over that time).

So let's recap. France has: far lower median wages, far lower wage growth, a higher poverty rate, a higher homelessness rate, dramatically lower GDP per capita, and an economy that hasn't net expanded in over a decade.

In 1980 France had a higher GDP per capita than the US. In 1990 France was just barely behind the US on GDP per capita. Today it's about $40,000 vs $60,000; that gap is persistently widening, with France falling down the global economic ladder by the year. It also explains why wage growth has been so extremely low in France over that time.
