What do you think about the fact snowball was awarded ‘animal hero: first class'?

I would support that decision.
At that time napoleon took the role as the leader of the farm, he never want to be held responsible for his mistakes and would always blame them to Snowball. But despite all that, Snowball still showed great loyalty to the farm and he also showed admirable bravery when the farm went to war.

By saying that,  FDR implied that he believed that American labors have hard work ethic.

"on the dole" refers to the phrase that describes a group of people who wanted to just receive money from the government without finding jobs.

FDR realized that despite their poor conditions, many unemployed households still did not want to receive any help from the government without working. Because of this, he included Government-funded jobs as one of the new deal's program.
