The social problem that The Jungle by Upton Sinclair described was B.) THE LIVING AND WORKING CONDITIONS IN CHICAGO'S STOCKYARD.
Not only in the stockyard but also in the meat packing factories.
The story is about how a family intent on pursuing their American Dream was not able to do so because they became victims of corruption, wage slavery, and oppression by the capitalists in Packingtown.
In life, almost all difficulties may be considered 'speed bumps' or some other similar word from reaching their own goals.
There are, in my opinion, three main types of obstacles, which are;
-Physical
-Mental/Emotional
-Outside (AKA Obstacles out of your control)
There are countless possible obstacles for each category, but to name a few for each;
-Physical difficulties may include an injury that would prevent an activity-based to be achieved or a disease that affects your inability to move towards a goal.
-Mental/Emotional goals can include disorders, diseases, or certain negative events occurring that can hinder your ability to function normally.
-Outside obstacles can be anything from weather cancelling an event you wanted to complete to a person having to opt out of something you needed them to partake in.
In conclusion, there are countless stops that resist against human goals.
