There's a movie on Netflix called The Platform. It summarizes capitalism perfectly!

The movie is set in a prison-like structure with multiple levels, where prisoners have voluntarily signed up for an experiment. In the center of this structure, there is a large platform with food that starts at the top and moves down through each level. Every day, the food is placed on the platform at the highest level, and it moves downward, allowing people on each level to take as much as they want. However, the people at the top often take more than their share, leaving very little or none for those below. If you're unlucky enough to be placed at a lower level, you might end up with no food at all, since those at the top take more than they need, and by the time the platform reaches the lower levels, it's empty.

If everyone took only what they needed, everyone would get enough food, but greed and selfishness make it impossible for this system to work fairly. Those at the bottom suffer the most, sometimes starving to death if they're stuck there for too long.
