Here is an article by Victor David Hanson that gets close to identifying the spiritual malaise of the country. The reason behind the reasons for what he feels is that we are a nation that has rejected God: Isa 5:20-24
20 Woe to those who call evil good, and good evil;
Who put darkness for light, and light for darkness;
Who put bitter for sweet, and sweet for bitter!
21 Woe to those who are wise in their own eyes,
And prudent in their own sight!
22 Woe to men mighty at drinking wine,
Woe to men valiant for mixing intoxicating drink,
23 Who justify the wicked for a bribe,
And take away justice from the righteous man!
24 Therefore, as the fire devours the stubble,
And the flame consumes the chaff,
So their root will be as rottenness,
And their blossom will ascend like dust;
Because they have rejected the law of the LORD of hosts,
And despised the word of the Holy One of Israel.
If only God can heal us.
