Trump claims "The U.S. will generate more than $17 trillion in investment this year"

According to BlockBeats, on September 18, US President Trump claimed at a press conference that "the United States will generate more than 17 trillion US dollars of investment this year." Regarding this remark, economist Peter Schiff said that this means U.S. GDP growth will surge by about 50%, and the dollar will soar due to capital flows. So, this statement is obviously nonsense.
