On January 29, 1850, the 70-year-old Clay presented a compromise. For eight months members of Congress, led by Clay, Daniel Webster, Senator from Massachusetts, and John C. Calhoun, senator from South Carolina, debated the compromise. With the help of Stephen Douglas, a young Democrat from Illinois, a series of bills that would make up the compromise were ushered through Congress.
<span>According to the compromise, Texas would relinquish the land in dispute but, in compensation, be given 10 million dollars -- money it would use to pay off its debt to Mexico. Also, the territories of New Mexico, Nevada, Arizona, and Utah would be organized without mention of slavery. (The decision would be made by the territories' inhabitants later, when they applied for statehood.) Regarding Washington, the slave trade would be abolished in the District of Columbia, although slavery would still be permitted. Finally, California would be admitted as a free state. To pacify slave-state politicians, who would have objected to the imbalance created by adding another free state, the Fugitive Slave Act was passed.</span>

I tried to answer your question but it didnt let me so im going to try to comment i
Advantages:
From a conservative or state-based ideology: it is much easier to control population since they rarely receive "strange" ideas or influence from outside. Domestic policies become much more important. In so, it becomes easier to set popular aims targeting citizens.
The country could(historically seen) stand the best defense against outside powers which could try to set an invasion. For example, the Great Wall of China turned out to set a strong defense against Mongols and other menaces along many centuries.
Disadvantages are listed:
Trading with other countries can influence negatively on economic growth, as there is no autonomous country even if it results as big as China.
Trade has become key in today's globalized world, henceforth the need to collaborate or cooperate in economic exchanges is a necessity to keep up the pace in global affairs.
