I care about what happened 30, 40, and even 75 years ago, and it's important for people to understand history in order to lessen the chance that it will be repeated.
A lot of what the middle class is going through now is a result of policies that were put into place in the 80s (income inequality, lack of investment in infrastructure, lack of exposure to different viewpoints on the media, etc), and a lot of these things have developed over decades. The more people who understand this, as opposed to thinking it's all because of the current President, the better off we'll be. It took us decades to get here, it won't be fixed overnight-especially if you vote for somebody who's going to expand the policies that caused it in the first place.
And I'm aware that there are many who won't get the message. I'm hopeful that enough people can.
