Nationalized industries are sectors of the economy that are owned and operated by the government rather than private individuals or companies. This often includes essential services such as energy, transportation, and healthcare. The goal of nationalization is to ensure that these services are accessible to all citizens and to promote public welfare over profit. Governments may nationalize industries to stabilize the economy, control prices, or provide jobs. In some cases, nationalization occurs during times of crisis, such as economic downturns or war. Countries like the United Kingdom and India have historically nationalized various industries to achieve these objectives.
