As BF said, "The only thing we can be sure of is death and taxes".

We still find the greedy hand of government thrusting itself into every corner and crevice of industry, and grasping at the spoil of the multitude. Invention is continually exercised to furnish new pretenses for revenue and taxation. It watches prosperity as its prey and permits none to escape without a tribute.

— Thomas Paine, The Rights of Man
