Looks like he drew exactly the opposite conclusion of what the article seemed to intend. That is, the super wealthy (like hedge fund managers) would get way more out of his tax plans than average and low income earners.

Sure, if you are one of those super wealthy hedge fund managers Trump's tax plans would make sense. The irony is that the vast number of ardent Trump supporters are working class lower-middle to low income earners.

From Salon Magazine - "The New York Times recently ran a report on “Trump geography,” seeking to solve one of the most bizarre mysteries of modern political history: Why do people support Donald Trump, and who are these people ?"

What did they find ? Salon dug deeper and wrote -

"Journalists found that in the counties where Trump is most dominant, there are large numbers of white high school dropouts, and unemployed people no longer looking for work. An alliance with the incoherent personality cult of Donald Trump’s candidacy correlates strongly with failure to obtain a high school diploma, and withdrawal from the labor force.

The counties also have a consistent history of voting for segregationists, and have an above average percentage of its residents living in mobile homes. Many conservatives, and even some kindhearted liberals, might object to the conclusions one can draw from the data as stereotyping, but the empirical evidence leaves little choice. Donald Trump’s supporters confirm the stereotype against them. The candidate himself even acknowledged the veracity of the caricature of his “movement” when he made the odd and condescending claim, “I love the poorly educated.” His affection for illiteracy and ignorance did not extend to himself or any of his children, all of whom have degrees from some of the best universities in the world."
