Saying any country is the greatest in the world is propaganda pure and simple. We are raised to believe this.
I admit I believed this without even really realizing it until I reconnected with our family in Europe in 2000. In many ways their little country of 2 million is far superior to ours. We witnessed a sense of community that doesn't exist here anymore. People care that their neighbors have opportunities for housing, education, and healthcare. Going to the open air market was phenomenal, I've never experienced community like that before. People know everyone and know where their food comes from. Even today in this small country, Slovenia, anyone from around the World can go to college here free and they have 100 classes taught in English. They love diversity and want their students to learn about the world, what better way than to invite people to join them. They also offer free college for retired people, always looking to better themselves. They aren't super wealthy nor is anyone super poor. They have some worldwide companies there. I may retire there someday.
