I think the impact that "muckracking" had on Americans was this:

Due to the mishaps and the loss of trust that some Americans may have for their own, state, county, or even government that used some points of "muckracking" to begin. The best examples of "muckracking" in history can be accountable in today's day in age of the 21st Century. Now, for the most recent events on the other hands we could go on about lists and lists about things such as Donald Trump and Stormy Daniels and so on and so forth (But we won't talk about those begin again, this is only meant to answer your question, not bring up another :D but then again, we all differ from opinion) Now back to the point- I think that the best common examples of "muckracking' in today's society would be through celebrities and politicians. Many of the paparazzi try to capture celebrity photos, but also grab their opinions about things, but then twist and divert the story in a whole other way. But the same goes for politicians except using a different method. Anyways this is my opinion on how I see "muckracking" and how it has impacted Americans.

I hope my opinion and answer to your question was able to clear up some things. If you have any more questions about this or need another opinion on it- or if you simply just have another question that you would like to have answered, please check out my profile and I will be happy to do so. Again, I hope this was helpful to you, have a wonderful day! :)
