What are the ways life has improved and worsened in animal farm?

At the behest of the Napoleon pig, the life of the farm "improved" only for the pigs, and only on the level of productivity, and the fact that the pigs dressed like humans, gaining allies in the other farms; however, it all actually worsened because the original Seven Amendments were disappearing until the dictatorship of the pigs was complete: the animals under Napoleon's command work very long hours, achieving very high levels of productivity, eating very little food, and without being able to complain before the pigs of those deals. The worst part was the change of commandments, when a amendments says: that all animals were supposedly the same, but some were more equal than others, giving a reference to how discrimination can be disguised in human societies.
