Good morning Justwood00. It seems as though you don’t know much about systemic inequality in the United States. I strongly suggest you read up on it. I have included some links in this comment to help you.
I can also assure you that USA is absolutely not the greatest country in the world. We lag behind other developed countries in health care, the UN health index, and even in democracy and free speech — supposedly our greatest assets. We have been fundamentally unable to contain a virus that plenty of other countries have largely beaten, causing the deaths of over 130,000 people. Jesus Christ cannot “fix” that.
Here are some resources — I hope you enjoy them!
I also suggest you read some Medium publications that tackle this topic: An Injustice! Zora, and Level are good places to start!
