What is the difference between economics, finance, business degrees?

Wondering what is the difference between economics, finance, business, marketing, accounting degrees. Can someone provide a very brief description of each? Also, which one would be the best option if I wanted to become an analyst for a firm like Goldman Sachs?

Economics: Studies and Analyzes the growth an economy and studies the production, distribution, and consumption of goods and services in that economy.

Finance: Studies and addresses the ways in which individuals, businesses, and organizations raise, allocate, and use monetary resources over time.

Business: How to make a legally-recognized organizational entity existing within an economically free country designed to sell goods and/or services successful.

Marketing: The study of the social process which satisfies consumers' needs and demands

Accounting: The art of measurement, statement or provision of assurance about financial information primarily used by managers, investors, tax authorities and other decision makers to make resource allocation decisions within companies, organizations, and public agencies.

If you want to be an analyst then you need a finance degree or an economics degree (at least a Masters/MBA). An analysts' work is math intensive.
