Comment re states without income taxes.
Government taxes come in 3 basic varieties: income, sales or property.
States that don't have income taxes substitute relatively high property taxes and/or sales taxes instead.
Property taxes, mostly based on real-estate ownership, are effectively wealth taxes.
Sales taxes, perhaps the simplest to administer and most difficult to evade, are often characterized as regressive.
All tax laws end up riddled with arcane, constantly-changing rules on exemptions, exceptions, exclusions, etc. and that's what the real problem is.
So what's the most equitable tax poison?
