&gt; I&#x27;m skeptical that&#x27;s a significant factor, because right-populists seem to be gaining even in countries, like Denmark and the USA, which have a large portion of mainstream media and politicians hostile to mass immigration.<p>The populist complaint against rightist politicians in the United States is that they claim to oppose illegal immigration, but that&#x27;s actually just a scam to fool the rubes into voting for them. When push comes to shove, they quietly endorse the current (Democratic) administration&#x27;s policies on the matter and make sure that efforts to block them always fail. Given that, the factors behind Trump&#x27;s support aren&#x27;t so different from the factors behind support for populists in Europe.
