I think that, fundamentally and strictly speaking, progressive taxation doesn&#x27;t qualify as &quot;dealing&quot; with the problem. It&#x27;s not a solution, it doesn&#x27;t even <i>attemp</i> to solve it. It&#x27;s just a quick bandage; an attempt to minimize.<p>And, empirically, you can see it. In my country (Portugal), with a supposedly agressive progressive taxation, inequality measures (Gini and Palma) are increasing. And the amount of luxury cars too. :)
