Why do you think Snowballs various projects, except the reading and writing classes, were failures?

Another way to look at this may be the following: The
constant variable with most dystopias and with any other society in which rules are
implemented for the benefit of a small, powerful minority is that the inevitable always
happens: Personality infuses what is supposed to be a firm, rigid, and objective plan.
In the case of Napoleon and Snowball, there was a clear conflict of character and a
power struggle that clearly showed the double intention of any plan proposed by
Snowball.

Similarly in society, when a small fraction of
power hungry people attempt to dominate a huge following, their hunger for power is
demonstrated equally in the way they pretend to implement their
plan.

This is why most faction-type governments such as
Hitler, Stalin, Mussolini, and the likes end up becoming failures and never last:
Because the human thread is too obvious and the personality of the ruler interferes with
what is meant to be general and universal.
