The political ideology that advocates for minimal government intervention in personal and economic matters is libertarianism. Libertarians emphasize individual liberty and personal responsibility, arguing that individual choices should guide both economic and social spheres without undue government influence. They often campaign for reduced regulations, lower taxes, and limited government functions, aiming to maximize personal freedom and minimize state control. This ideology contrasts with systems advocating for public welfare and regulatory measures, positioning libertarianism as a distinct voice in the spectrum of political thought.
