How do we philosophically understand the US today?

US President John Adams answered your question for you:

"Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other."

The morals of the nation have gone down the drain and we are reaping what we sewed. The Constitution of the United states grants more liberty to the individual than immoral people can be granted. Immoral people have to be governed by a sever strict government. In the USA we have legalized the murder of infant children, and the latest statistics show we are murdering more than 2000 children per day.

Until America learns that the truth cannot be improved and remain the truth, and that a lie that's patriotic to large American corporation's and the American government CANNOT replace an unfortunate truth, America will continue on it's path to hell.

T he question is "How to fix it and even then there are people who do not want to fix it If Christ was born to-day in the U S with out his miracles just saying the things he said back then what would happen to him

The US isn't even a country, it's a corporation owned and controlled by numerous banking families.

America is biggest marketplace of the world.Everything is based on business in USA.

you cant mix the two. There are two people in life they will only conflict
