These concepts were flipped upside down, and if you study why, you'll see the reason is Biblical principles. All you have to do is read many founding documents to see this.
John Adams wrote "Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other." Why would he say this? Think about it.
I'm not experienced enough to describe or explain why America has done bad things throughout history. We all make mistakes, and we are all unique. I'm sure corruption existed throughout our history. My personal feeling is that between 1900 and say now, Americans are more willing to reject the reasoning that gave it freedom to accept the reasoning that will take it away.
This rejection starts not only at the bottom but at the top. Many Ivy League colleges were founded to educate and raise missionaries. Why? Perhaps to spread the message of freedom and liberty. What are they doing now? The exact opposite. Think about that.
Many here will argue it's a good thing. So be it, but it doesn't make it anymore true than the message I'm sharing.
