Liberal theory is a way of thinking about how society should be organized. Its ideas come from the belief that people should have freedom and that being able to choose is important. This means that people should have the right to decide how they want to live and that governments should ensure that people can do this by making laws that protect their rights and freedoms. Liberal theory also believes in democracy, which is a system of government where people choose their leaders and laws by voting. Liberal theory supports governments that provide services to citizens, such as health care, education, welfare, and so on. Finally, liberal theory also supports free markets and trade, believing that they help create wealth and provide people with the opportunity to better their lives.
