A new analysis by Oxford Economics, a British forecasting firm, says that a Donald Trump presidency would cost the United States economy $1 trillion over five years.
So much for his heralded business acumen.
Oxford Economics found that if fully implemented, Trump's economic, tax and immigration policies would cost 4 million U.S. jobs, weigh down global growth and U.S. consumer spending, and could spark a trade war with other nations.
Jamie Thompson, head of macro scenarios at Oxford Economics, said Trump’s efforts to help Americans could actually backfire.
In Oxford's "adverse case scenario" Trump slaps a 35% tariff on goods coming from Mexico, like cars and air conditioners.
A Trump economic advisor agreed things could be tougher.
Trump's team acknowledges that a grocery trip would become more expensive with tariffs on other countries' goods.
"(Prices could go up) if those tariffs were actually enacted as proposed," Tom Barrack, one of Trump's economic advisers, agreed in an interview with CNNMoney's Cristina Alesci.
