Yea, because governments are so starved of income and spend every penny like it's precious they need to more tax income.  /sarcasm

In 2016, federal and local governments in the United States collected an estimated 6 trillion dollars.  That number is so large our brains can't comprehend it so it subconsciously skips it.  If you earned $40,000 a year, it'd take 150 million years to accumulated that same 6 trillion.  If you stacked $100 bills they'd stack 3,780 miles high.  A 6-trillion second time travel would put us at roughly 180,000 BC.  

Just think, governments in the United Stated collected that in one year... AND they're still running a deficit.
