Same thing. Just kidding. But I'll take it except:
They don't teach how taxes work except in vague generalities. 
But what of the complicated deductions that are sophisticated because they are designed to address a specific goal. For example, a person with their own business, filing jointly with a wife who makes 5 figures. His business always loses money. But he can take some things as a business expense, must claim income, but then they deduct is loss from her income so she pays less tax. It's rather complicated.
Seems if it gets more simple, then some things have to go. Which may not be a bad thing.
