Answer:
Arthur Miller wrote The Crucible to show the different reactions towards hysteria that was instilled in others through fear. The Salem Witch trials outlined the communistic ways that the government handled things. Considering that a simple rumor of witchcraft led to the hanging of civilians, it took around a year for people to realize that it was morally wrong. Miller also wrote this play to show a comparison of his life during the 1950's to the 1690's and how they were significantly different. People continue to read it because it symbolizes how society handles different scenarios when they are panicked, which can lead for it to end in tragedy. It allows you to understand the past and compare it to the future.
While on the subject of past and future, remnants of The Crucible are still shown today through the Coronavirus pandemic. When the pandemic started, citizens panicked and were drove to the point of hysteria because they didn't know how to handle it. While this would be the expected reaction, considering we haven't dealt with this form of a pandemic since the H1N1 virus (swine flu) broke out, it caused people to panic-buy toilet paper and push away any close friends in fear that they could have it and possibly spread it to their loved ones. The fear is still relevant months later, even with the vaccine. A lot more people are becoming comfortable with our reality, but there are still those who try to push others to wear masks and take precaution.
