What were the goals of the fireside chats and were they accomplished? what language does fdr use to persuade his audience?

The goals of the fireside chats used during World War 2 and the Great Depression by President Franklin D. Roosevelt were to inform the public people about what was going on in the government. Roosevelt also used these fireside chats to calm down the citizens, and to tell them that everything was going to be all right. Fortunately, yes, the goals of the fireside were accomplished. 

FDR, or Franklin D. Roosevelt, used very persuasive yet simple language, so that everyone would understand what was going on and wouldn't panic, because a farmer who wasn't as educated as the common man is still a citizen.

Given that the FDIC is in charge of protecting the money in a bank in case that such bank goes info bankrupt, and that the SEC is a part of the USA government that protects the stock market and its movements, it can be assumed that this agencies are in charge of protecting the money and investments of the citizens. For example, the FDIC is allowed to protect and return up to $250.000 in case that someone is about to lose their money because the bank will go bankrupt. The SEC is the commission that will regulate any inusual behavior in the stock market that could result into a financial crisis.
