It's

what they always do:

"In July, the nonpartisan Tax Policy Center estimated the impact of a “Trump-like plan.” Howard Gleckman, a senior fellow at the tax center, wrote that middle-income households (those earning between $50,000 and $86,000) would see an average tax cut of about $1,900 or about 3 percent. But the top 1 percent (those earning more than $732,000) would get an average tax cut of $270,000 or nearly 18 percent, and the top 0.1 percent would see a 20 percent tax cut."

“Forty percent of the benefits would go to the top 1 percent,” 

It never "Trickles down." Never has, never will.

Trump’s Tax Plan and ‘the Rich’

It's that much more we could give away if it passes I suppose.
