Trump's chief economic adviser, Gary Cohn (former president of Goldman Sachs), spoke of this misguided policy of pushing near zero interest rates and currency devaluations at a Institute of International Finance sponsored event  in the 2016 G20 China.  He said using such old policies does not work in the modern world. And that if global interest rates were 3% higher the world would be a better place as insurance companies, pensions, would be viable and investors can put their money back into bank deposits, government bonds instead of financial products which face liquidity problems.
