"Some people argue that big companies have a good effect on society, while others do not. Personally, I think such corporations have a great effect on society for the following two reasons. Firstly, huge companies enhance the economic consumption in the country. Since they spend a huge amount of money, national economic circulation rates are rising. Big companies contribute to the economic activation. Secondly, products manufactured in corporations improve the quality of life. Such products are sophisticated due to tremendous inspections or manufacturing machines used in big companies. Items produced by big firms satisfy the needs of many customers. For these two reasons, making economies in these countries more active and satisfying a large number of people with their products, I believe that big companies have a positive effect on society."

Is this expression natural?
