Why would leaders in Iran want to limit American cultural infusion?

american corporations would become to powerful

Iran is to poor to support a great american cultural infusion.

american ideas conflict with traditional iranian ideas.

american culture is too religious,

Iranian leaders do not like American culture with its excess and what would be considered loose morals in that part of the world. Many Americans drink alcohol, which is not acceptable in Iranian society. Women dress immodestly, tattoos and piercings are acceptable in most of America, and sexual relations are less restricted. Americans tend to spend excessively, which would be difficult for a poor country like Iran. America's religion is very different from Iranian religion.
