Every tax plan is an experiment. (&quot;Trickle-down effects?&quot;) Every law is an experiment. (&quot;Three-strikes?&quot;)<p>Remember, this NYT article was written by a conservative, who previously was a senior fellow at the Manhattan Institute for Policy Research, a conservative think-tank with the goal to &quot;develop and disseminate new ideas that foster greater economic choice and individual responsibility&quot;. Before that he was a &quot;commercial real estate banker at Wells Fargo&quot;.<p>There&#x27;s no need to believe that any of his statements are false, but I can&#x27;t help wonder why there&#x27;s a focus why &quot;Bernie Sanders’s Tax Plan Would Test an Economic Hypothesis&quot; when every one of the candidates has an economic hypothesis to test. Even if it&#x27;s the most extreme (and I think continued tax cuts for the rich and funding multiple overseas wars are also rather extreme), I can&#x27;t help wonder if there is a bias towards which sources to draw from when writing this article.
