France gdp/capita is around 43,658.98 USD. 47% is $20.5k/capita.
US gdp/capita is around 66,000 USD. 40% tax revenue is $26.5k/capita.
The US government brings in 30% more tax revenue per resident than the French government.
The differences in social benefits between France and the US are not due to lower taxes in the US. They are due to inefficient spending and systemic economic differences.
