Companies dominate the world sphere in terms of influence and raw monetary power. Though sometimes kept in check with government regulations and systems, corporations can still often run rampant with greed and power. In many cases, the main priority of large businesses that are publically traded is to satisfy their shareholders and investors, with other concerns, like social responsibility falling by the wayside. In America alone the top 50 companies have a combined market capitalization, meaning the market value of outstanding shares of stock, of more than $12 trillion. The wealth that these organizations flout is not to be underestimated. Here are 10 of the largest public companies in the US.
