A lot of it seems to come from finding good conditions on which to bin data, though the bin categories do not seem highly artificial or cherry-picked, to me.<u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">I got to the above from an article by Edsall that, again, seems to me well-sourced:<u></u><u></u></p></div><div><p class="MsoNormal"><a href="https://www.nytimes.com/2020/12/09/opinion/trump-social-status-resentment.html" target="_blank" rel="noreferrer">https://www.nytimes.com/2020/12/09/opinion/trump-social-status-resentment.html</a><u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">So probably necessary to refuse to speak in sound-bites about income or wealth mobility, and to use more complete sentences that refer to specific conditions, even though if one has that granularity, there are interpretations of the sound-bite that mobility has been badly impaired that still seem correct, to me.<u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal">EricS<u></u><u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div><div><p class="MsoNormal"><u></u> <u></u></p></div></div></div>- .... . -..-. . -. -.. -..-. .. ... -..-. .... . .-. .<br>
