Answer:
To prevent monopolies and oligopolies in economies.
Explanation:
Monopolies are organizations that have almost entire control of markets. <em>If I ran a monopolistic oil company in the US, I could in theory control the cost of oil by raising it higher/lower than any competitor and charge lots of households many more had there been competition.</em>
Oligopolies are organizations that work together to cut out competition, with the exception of the corporate ally. <em>If my buddy and I ran an oligopoly on oil, we would have control of the entire market together and control the costs of oil, in theory.</em>
Hope that helps, best of luck!
