This answer is based on opinion, so I wrote as if I agree that there should be muckrakers.
I believe muckrakers are still needed today. Historically, muckrakers created public awareness of corruption, social injustices and abuses of power. The in depth encounter would bring national awareness to these issues, and would often bring change.
