The tax loading in the US on the equivalent of a 100,000 EUR salary is much lower than this.

At 100,000 USD (a bit lower than EUR) the combined tax load on income for both employee and employer is typically ~30-35% depending on locale. In the US, $100k is pretty close to the median household income.

If you have extremely high incomes (e.g. 1,000,000+ USD) the gap closes a bit but even in the highest tax locales the marginal tax loading maxes out at ~60% of top-line income.

US Federal tax rates are some of the most progressive in the world. Only ~20% of households are net taxpayers after transfer payments and subsidies. Ironically, this is why it is so difficult to significantly increase income tax revenue in the US. It would require the middle-class majority to vote to raise their own taxes.
