Eugene V. Debs discusses how socialists in the US strive for financial and social equality among all US citizens. Debs describes how American society can be extremely unfair, as some individuals are born into wealthy families and never have to work a day in their life while other individuals work extremely hard their entire lives just to survive.
This is why Debs, and socialists in the US in general, strive for a system in which the government has more control of the means of production and the economy in general. Debs argues that all things in the US are jointly used and that it only makes sense for the government to be involved in making sure these resources are spread out equally to citizens.
I would say a key feature of the European Renaissance culture would be that, because of the Renaissance, things such as reading and knowledge of things became much more popular, creating a more educated population. Classical literature became popular once again too. There was also the fact that humanism emerged during this era, which was basically the individual thought and self-admiration of human beings rather than human beings being despicable, unworthy beings under God. People like Michelangelo, Da-Vinci, and Raphael were amazing artists that could show examples of humanism in their artworks, especially da-vinci with his sketches. hope this helps ya :)
