We're in agreement philosophically; however, it would be a “hard sell” to those who believe they will lose income sustained by tax deductions for the wife and 2.0 kids.
My suspicion is, now that our federal government is redistributing wealth thru “earned income credits” for those who have never held a job and have no legal means of support (other than the government dole), the average taxpayer would probably come out better if we abolished dependent deductions and earned income credits and reduced taxes by an amount equal to what could be saved by the elimination of those practices.
That said; it would still be a very “hard sell;” given the complexities and politicians propensity for massaging the truth into something more beneficial to their own wealth accumulation and sustained power.
