Neoliberals have no comradery and see each other as competition. They look for opportunities to tear each other down instead of supporting each other, thus making their community weaker as a whole.
Whereas the communists support one another and seek to help build their community as a whole, thus leading to a stronger, more supportive community.
"The animal species, in which individual struggle has been reduced to its narrowest limits, and the practice of mutual aid has attained the greatest development, are invariably the most numerous, the most prosperous, and the most open to further progress."- Peter Kropotkin
TLDR- Sucks that you don't have our level of solidarity, libs.
