All answers of the future are in the past

Since I can remember, I lately been thinking that most of the answers to the daily problems have already be solved in the past. I realized this thinking because of being delegate at MUN’s (Model United Nations), every time we finished a resolution for a futuristic or nowadays problems I have been noticing that those problems have already happened before in time, an example: we were debating of what will nations do to all the unemployed people because of automatization in industries, later before analyzing the problem I understood  that this problem has already happened in the 1800’s at the industrial revolution and by that it have already been solved.
