"Concentrated power is not rendered harmless by the good intentions of those who create it."
Source: Capitalism and Freedom
Explanation
Good intentions do not cancel the risks of concentrated power. Even the kindest architects cannot rewrite human nature, and power tends to outlast—and outgrow—their noble hopes. What begins as a tool for good can become a weapon in the wrong hands.
That is why wise systems limit and separate power, keep decisions close to the people, and insist on transparency and accountability. Trust in virtue is not a safeguard; good rules are.
