Final answer:
The main idea of the quote is reflected in the U.S. government today through the life tenure and protected compensation of federal judges, including those on the Supreme Court, as established by Article III of the Constitution to ensure judicial independence.
Step-by-step explanation:
The quote 'He has made Judges dependent on his Will alone, for the tenure of their offices, and the amount and payment of their salaries' reflects concerns that were addressed by the framers of the United States Constitution when they established the judiciary. The U.S. government today reflects the main idea of this quote by ensuring that federal judges, including those on the Supreme Court, have life tenure 'during good Behaviour,' and receive a compensation that 'shall not be diminished during their Continuance in Office.' This is outlined in Article III of the Constitution. These provisions were designed to maintain the judiciary's independence from the other branches of government and prevent undue influence over the judicial process.
Therefore, unlike the scenario described in the quote where judges' tenure and salaries were controlled by a single ruler's will, the U.S. Constitution protects federal judges from such external pressures, allowing them to make decisions based on the law and not on political considerations or personal interests.
