Are there any alternative tax mechanisms to income taxes that you'd support? I've heard many times that VAT or consumption taxes are far more efficient than income taxes. Seems like they're also easier to enforce (except in regions with significant black markets). I've also heard that taxing land & non-invested property is a good idea, too.
