Has the United States been re-venued into 'the crown's' feudalistic system of governance?

Lack of meaningful work and loss of property causes stress. And, long term stress can lead to serious health problems.

So; What form of government has the United States?

And, what is "the crown"?

(For a prophetic perspective on this subject, see also Isaiah 28 and, consider from Strong's Hebrew Dictionary, the double meaning of "crown".)
