The animals can’t remember what life was like so the pigs can take over. They just say Napoleon is right in whatever he says. They never think for themselves and never have any opinions. They were very easily persuaded and just went with whatever happened. It’s like their blind and can’t see the right direction.
The animals also can’t read. They couldn’t read the commandments so they couldn’t see them change. They also couldn’t read the statistics and couldn’t see how bad it was for them. They let Napoleon be in charge and because of that they
were uneducated and were very tractable. The animals needed to stay up with reading because then they couldn’t see what was wrong
The animals just let the pigs lead and say Napoleon’s always right. As a result the pigs can do whatever they want and squealer just backs it up with false facts. The animals think that it will be less work to just let the pigs lead and they are very lazy. The pigs are awful and make terrible decisions.
