Many tax experts said Trump’s latest speech reveals an even sketchier picture of his economic vision than previous proposals.

“In general, it’s less clear of a tax plan than it was before,” said Ryan Ellis, a senior fellow at the Conservative Reform Network.

First, Trump pitched new, less aggressive tax cuts and appeared to be backing away from his pledge to end tax liability for 75 million households. Then he introduced a proposal for an investment income loophole that could actually benefit hedge fund managers and suggested a tax break for child care that would do little for the lowest income earners.

“He’s actually doing less for the middle class than he originally planned,” said Martin A. Sullivan, the chief economist at Tax Analysts.

Ellis, who previously served as the tax policy director for Grover Norquist’s group Americans for Tax Reform, said Trump’s proposal to allow parents to deduct the cost of child care would provide no benefit to low income workers and single parents who are unlikely to have any tax liability to begin with.
