Final answer:
America tends to excel in the principle of Individual freedom, as it fosters civil liberties and the pursuit of the American Dream. It's a reflection of the worth of the individual, allowing personal freedoms with a balanced government approach, even though ongoing debates over equality and social justice continue.
Step-by-step explanation:
When assessing which key principle of democracy is being well implemented in America, a compelling argument could be made for Individual freedom. This principle, deeply engraved in the American ethos and reflected in various constitutional protections, emphasizes the importance of civil liberties, allowing citizens to express themselves, practice their religions, and engage in a multitude of other personal choices without undue government restriction.
The American Dream is another aspect that showcases how America has historically prioritized the principle of equal opportunity, allowing individuals the freedom to pursue wealth and improve their standard of living, which can be seen as an extension of the worth of the individual in a democratic society.
However, it is important to recognize that the balance between different democratic principles, such as liberty and equality, often involves trade-offs. Whilst Americans enjoy a high degree of individual freedom, ongoing dialogues on issues like economic inequality and social justice highlight the complex interplay between these foundational democratic values.
