The president is running out of time, and his tax returns just dispelled all his pretensions to wealth and sacrifice.
Remember: Back in 2015, when Donald Trump announced his campaign for president, about one-third of Republicans and Republican-leaners condemned the distribution of wealth in the United States as unjust. Those class-aggrieved Republicans believed that high-earners paid too little in tax and wanted taxes on corporations and rich people raised, not cut. Those were the Republicans who rejected Jeb Bush and Ted Cruz—and elevated Trump as the party nominee instead.
Trump voters were more economically pessimistic than other Republicans. They were more racially aggrieved. They identified themselves as people who worked, who were mooched upon from below and exploited from above.
