In his dreams, Old major criticizes humans. What are three reasons he doesn't like man?

Old Major feels man treats animals as an expendable resource. Animals are abused and treated as slaves. They are also fed only enough to survive and are finally slaughtered when they are considered no longer of use.

Old Major believes that:

1 They (animals) are no treated equally by humans, and that they are overworked.

2 They (animals) believe that they are not getting feed enough

3 They (animals) also feel that when the humans think that there is no use for them anymore they are killed
