If you earn 45000€ or more per year (post-tax) you are in the 1%. (According to this)
€45,000/yr is in top 1% globally, but not the top 1% for the EU. Either way, the article is discussing a tax on wealth, not income. Even if €45,000/yr was in the top 1% income for the EU, someone making that salary is extremely unlikely to have accumulated enough assets to place them in the top 1% for wealth.
Yes 45K is the global Top 1%. But in the quoted parts they are talking about the global 1% and frame them as “ultra-rich”. Not just the EUs Top 1%.
The richest 1% of the planet own nearly half of all wealth. These same ultra-rich emit more CO2 than the poorest half of the planet.
