Chicago math is practiced in DC.
It's difficult to explain the intrinsic nature of how the numbers react and relate, so I'll show you by using an example:
Suppose you have a nation that is 14 Trillion dollars in debt.
You then create a program that SPENDS an additional Trillion dollars, with most of it going to non-essential fluff that was promised to the states of those who authored the bill.
Now, mathematically you've got 14T + 1T.
In the olden days, this would equal 15T.
But by using Chicago Math, you're able to convince your voters that the addition $1T will somehow reduce the orignal $14T.
Amazingly, it works wonders. (the convincing. Not the reduction)
It's based on an ancient formula that traces it's roots back to an Eastern African nation.
But the example above is just a tease.
It's easy to use this logic and to then extrapolate many different scenarios.
One could, for instance, suggest that it is better for our economy to join hands in defiance of those who pay the most in taxes. But we'll leave this example for next years class.
