American conservatives believe that a large government poses a threat to individual liberty, they usually support and a strong national defense, traditional American values, and the free market are believed to provide great economic opportunity and benefit many people. On the other hand, Liberalist cherishes equality as the primary political view and they see the government as a necessary agent in promoting equality. Family and parents can influence one’s political outlook in positive or negative ways. Social groups can also play a role in where one stands politically. A big difference or dividing line is how Liberal policies generally emphasize the need for the government to solve people’s problems. While Conservative policies generally emphasize the empowerment of the individual to solve problems. An example could be the welfare system. Liberals support welfare because it provides for the poor without welfare life below the poverty line would be intolerable. However, conservatives oppose long-term welfare because they believe there should be opportunities to make it possible for poor and low-income workers to become self-reliant.
Althusser’s definition of ideology is how ideology can be a very useful tool that exists primarily in school, media, and politics. Since school is mandatory for all kids the ideology in schools plays a huge role in our society. School is a powerful ideological state apparatus because they are forced and it’s a way to get kids to think in a certain way, behave and comply with authority that will prepare them for the future.
