Final answer:
The spoils system employed by Andrew Jackson paved the way for him to expand the powers of the presidency and presidential appointees. It also revealed the potential for scandal and corruption in American politics.
Step-by-step explanation:
The major significance of the spoils system, as employed by Andrew Jackson, was that it paved the way for him to expand the powers of the presidency and presidential appointees. The spoils system involved the appointment of political loyalists to government positions based on party loyalty. By filling federal posts with his supporters, Jackson was able to strengthen his influence and control over the government.
This system also revealed the potential for scandal and corruption in American politics. Some appointees took advantage of their positions for personal gain, resulting in instances of corruption and embezzlement. Notably, the spoils system in Jackson's administration led to the first case of embezzlement against the government.
