In a perfect world without greed and corruption, I would agree with you. However, I live in Brazil, where the state is constitutionally mandated to provide all basic necessities (healthcare, education, etc.) and we have one of the highest tax rates in the world. Additionally, corruption here is absurd.

Despite having enormous budgets, the services the state provides are inadequate. Many people choose to sacrifice an additional portion of their income (on top of what they already pay in taxes) to access these services privately. Even with extensive social policies and taxes on virtually everything you do — salary, consumption, transfers, inheritance, literally everything — quality of life remains poor. High tax rates actually breaks development.

We must be cautious about supporting policies that tax the wealthy more heavily, because when the state considers someone earning $2,000 per month to be 'rich'—which already happens, as evidenced by the current income tax brackets (IRPF)—these measures won't improve anyone's life.
