A business must adapt and overcome consumerism and ecology, and it has a social responsibility to do so. Cultures surrounding businesses also play a major role. A business must adapt to a changing society with age, lifestyle, culture and location. When a business learns to adapt to these changes, it will be profitable for both the business and consumers. Economic systems can be classified into three categories. These include capitalism, socialism and communism. Pure capitalism is an unrestrained freedom to buy, sell and compete. Private enterprises allow entrepreneurs to run businesses without central government control and can operate within a free market. Capitalism is a system of true private enterprise. Some aspects of capitalism are free choice, private ownership, private profit and free competition. The only drawback of this type of system is that a company can operate with no competition thereby creating a monopoly unfavorable for consumers. Socialism, on the other hand, is a system where the production and distribution of industries are owned and operated by the government. Officials directly manage some or all of the extraction of raw materials, manufacturing, communication and transportation. This system is loosely regulated by the government. Finally, communism replaces the operation of a free market almost entirely. Most of the rights enjoyed within the capitalist system are denied and private ownership is prohibited. Business are controlled by state planners and competition is almost completely eliminated. Today our economy is made up of a mixed economic system with each one contributing but no one dominating. Communist and socialist systems seem to be adopting many capitalists views and ideas. It is up to you to decide which system you prefer, but the United States' system of capitalism seems to be working adequately and positively. It is based on the principles of private enterprise and modified capitalism.
