Yeah if you work a W-2 job and the company is making tax deductions from your paycheck, your taxes are pretty simple. If you have a mortgage, you can deduct the interest. I think most people are in this category. Taxes just start getting complicated proportionate to the creative compensation some jobs offer - deferred stock purchase programs, etc., - or if you have some complicated deduction or third-party income sources.

That's true, but you need to have other deductions or a fairly large mortgage for it to be worth taking that deduction instead of the standard deduction. Most people are better off with the standard deduction.
Most of the complications in tax policy are affecting a small minority of people and corporations.
