Actually no, the whole country would be worse.
If you are an IRS status quo supporter, you need to leave this forum. That thinking is not part of a “free republic.”
But setting the idea of a national flat tax aside for a second, whether or not it would be good or bad is not relevant to your comment about what it did in Pa. The best part of a flat tax is the simplification of the national tax code and the demolition of the IRS. Thus, no single state experiment has anything to do with what the impact would be nationally. Your analogy was a fail, period.
But I would like to hear why you think a flat tax would be bad. I can’t WAIT to hear your little thinking on this.
