Class Prejudice

There are many kinds of prejudice in our UGLY world with one of the few most major ones being class prejudice. I really do not get it, what is this 'classification', I mean like, putting different peopple in different groups? How could this even happen? We are living in such an UGLY world. Before, you go around protesting, let us analyse this situation first. Class prejudice seems to be a sight which one can see in any society in this world. This is definitely not something good for a society. If someone of a lower social class is under such bad pressure everyday, this could lead to a violent mentality in these people and the number of crimes will increase by a lot. I do not see a difference between people of different classes other than the wealth. I just cannot stand people who are very arrogant just because they are rich. It is not a serious thing in Singapore and I hope that I will not see such a sight in the years to come.
