U.S. President Donald Trump's erratic tariff policies have created "total random chaos," undermining his campaign promises to support working-class voters, according to policy expert Lori Wallach. The administration's on-again, off-again approach to tariffs is chilling investment and halting construction of new projects initiated under the previous administration. Wallach criticizes the administration for abusing tariffs, using them to threaten countries based on whims rather than strategic economic goals.
