Difference between a corporation, a sole proprietorship and a limited liability company

In 250 words, what is the difference between a corporation, a sole proprietorship and a limited liability company?  Review Citizens United v. Federal Election Commission 558 U.S. 310 (2010).

A corporation is a complex company with multiple employees. This business structure is suggested for larger, established companies. A sole proprietorship is a basic business structure, An individual owns the business and is responsible for its assets, as well as its liabilities, A limited liability company provides limited liability features of a corporation, as well as the tax efficiencies and flexibility in the operation of the business U.S. Small Business Administration, 2017).

In the case Citizens United v. Federal Election Commission 558 U.S. 310 (2010). Citizens United sought an injunction against the Federal Election Commission. Citizens United wanted to prevent the Bipartisan Campaign Reform Act (BCRA) from being applied to its film, Hillary: The Movie. The Movie discussed whether Senator Hillary Rodham Clinton would make a good president (Citizens United v. Federal Election Commission 558 U.S. 310 (2010).

I do not know if businesses should have the same First Amendment rights as individuals. In an article I found related to the topic, the author explained that businesses should not have free speech rights. The author claimed this is true because businesses are illegitimate participants of a political debate. Corporations are not humans or citizens. Businesses are not endowed by their creators with certain inalienable rights (Greenwood, Greenfield, Jaffe, 2007).

The authors of the article described that corporations spend money, and money isn’t speech. The second point is most business advertising and lobbying should be excluded from the First Amendment because it should be considered commercial speech (Greenwood, Greenfield, Jaffe, 2007).
