The social security act. it's been a bit corrupted since it was created, though. you might want to read up on it--it's pretty interesting.
Americans were very upset over the stamp act because they believed the British government did not have the right to tax them. They said that they shouldn't be taxed without their own representatives being able to vote for it themselves. "No taxation without representation" comes from this belief.
I know that the mass media can have a huge impact on public opinion, so maybe cause and effect? I'm not 100% sure, but I hope this helps! :D
