Genesis 47:20 And Joseph bought all the land of Egypt for Pharaoh; for the Egyptians sold every man his field, because the famine prevailed over them: so the land became Pharaoh's. [kjv]
47:26 And Joseph made it a law over the land of Egypt unto this day, that Pharaoh should have the fifth part; except the land of the priests only, which became not Pharaoh's. [kjv]
Many taxes, such as the income tax in the United States (to finance the Civil War effort), were started as temporary measures and were never removed.
The general rule is to add taxes for an emergency. After the emergency, remove part of the taxes, take credit for it, but leave a good part of the added taxes in place for eternity.
In Genesis, during the famine predicted by Joseph in the interpretation of the dream of Pharaoh, we see how big government can enslave people by using their power to tax, etc., against the people.
