Washington (CNN) Donald Trump's top budget adviser defended the sweeping cuts proposed to social, foreign aid and environmental programs in the President's budget on Tuesday, arguing that the White House could no longer ask taxpayers for money to fund programs they believe to be inefficient. Economists and Democrats have already panned the budget as a document that benefits the wealthy and cuts services from the poor. Mick Mulvaney, Trump's budget chief, rejected that idea on Tuesday. "We are no longer going to measure compassion by the number of programs or the number of people on those programs, but the number of people we help get off of those programs," he said, arguing that it is actually compassionate to cut government spending on inefficient programs.Economists and Democrats have already panned the budget as a document that benefits the wealthyThe budget assumes that the American economy will begin growing at 3% each year
