I have watched this movie once, this movie is also one of my favorite movie. I think that in that world is somewhat similar with our world.
The capital has luxurious facility but district 12 is just a rural area. Also the capital people tend to overplay themselves such as wealth and looking. At the beginng Kitniss looks feeble and weak but inside, she is strong, intrepid and dauntless. Who live in the capital they watching event as a tv show. But reality is cruel. They have to compete with each other to survive and also a lot of obstacles try to interrupt them and kill them.
For this reason, i think it is similar with our world. Because we have to survive from this socity but execpt us, they are indiffirent to us.
