Obviously your teacher wants to hear your thoughts about this subject; however, I will share a few ideas to help you start thinking about the subject in order to decide for yourself what you believe.
In general terms, people who can read are better off than those who cannot read. They will usually have better jobs and will advance much farther in life than those who cannot read. Those who cannot read are the people who generally do not vote because they cannot read a ballot and hesitate to see a physician because they cannot fill out the forms. And politics are out of the question for this group of people.
People who read non-fiction regularly are generally expanding their brains and can then use them to pursue education or politics, among other things.
Recent research has indicated that those students who read literature are statistically better thinkers (I have attached the link below).
“Exposure to literature may offer a (way for people) to become more likely to open their minds,” the researchers write in the Creativity Research Journal.
Good thinking skills are essential to managing crises, and all three of the things you mention are in a kind of crisis: health, education, and politics. People who read and think are able to create innovations and solve problems better than non-readers (again, this is a generalization); people who cannot read are dependent on others for virtually everything. People who cannot (or, even worse, do not) read will have nothing constructive to add to the national conversation about any issues, but especially these three important ones.
While I do not believe that those who do not read will be the primary cause of trouble in health care, education, and politics, they are certainly not likely to make any improvements in this area. In fact, they are likely to be the biggest complainers but have no means to enact change or move the discussion forward.
Reading fiction, in particular, requires effective critical thinking skills, and that is a valuable skill set for any field.
