"How are the different types of people treated differently? Why?

My question that I was curious about was, "How are the different types of people treated differently? Why?". I was curious about this because it appeared to me that some races in the game were treated better/worse than other ones. I went out and talked to some people I had found on my adventures to find the answers. One observation I found was that people were always worried whenever they say a Khajit. This is because apparently (after talking to a Khajit) Khajits are associated with being sneaky and being thieves. I found this interesting because I remembered when I was choosing a race that Khajit's had sneak and lock picking as their specialty. It was also interesting because as I went around adventuring I came across a thief that tried to rob me and take my stuff and it just so happened that it was a Khajit. This reminded me of real life because of all the stereotypes that are present. I found it interesting that the creators added this element to the game because this type of issue is just as apparent in real life. People tend to judge another person's intentions or actions based on what race they are in real life and I though it was very creative for this element to be included in the game. Another element I really thought was pretty creative to put in were the poor people living among the world of Skyrim. Not only did the creators include stereotypes among different races but they also did it among the same races. I found poor Nords along with poor Khajits and I'm sure I would've found more poor people among the different races if I continues to play.
