No, he's talking about total effective taxes in France. That includes things such as VAT.
Basically, the lower classes pay around 40% taxes (compared to their income). The middle class pay around 50%. Rich people pay around 30%, and the riches pay even much less (percentage wise). Apparently, wealthy people are better at exploiting loopholes in our tax system.
It doesn't explain everything however: The top 2% (or is it 0.2%?) pay less than 10% taxes. Direct income tax alone is supposed to approach 50% for those incomes.
