A statement which, in itself, is a generalization.

• Vacation (Annual Leave) for the EU is minimum 4 weeks (20 paid days) per year: https://en.wikipedia.org/wiki/Absence_management
• The US has no federal mandate for paid vacation, where the private sector average is about 10 vacation days after one year, plus about 6 paid holidays, totaling around 16 days annually: https://time.com/4227072/job-benefits-united-states/

In addition, some European countries have more, like Sweden’s legal minimum is 25 paid days per year, with a special rule for new employees hired after August 31 granting only 5 days until the next April. Sick days 1–14: Paid by employer at a minimum of 80% of salary, subject to a deduction, and from Day 15 onward: Compensation provided by the state, typically 80% for 364 days, then 75% up to 550 days, with medical certification and administrative reporting required. https://www.e-days.com/holiday-compliance-guide/emea/sweden

Even if what you said were true, the "stupid" Europeans have it better than the US.
