Are All Governments Corporations?

When did the governments of our nation become a corporation? This happened back in 1871 when Congress incorporated the United States and moved the capital to Washington D.C. which is foreign territory. We had no idea that this had taken place and Congress had no right to change the status of the United States. The people did not vote for this change.

Now corporations run all 50 states and the Federal Government. How can a corporation run the government of the United States? Each time we vote for the President of the United States, we are installing a new CEO in the corporate office.
