LOS ANGELES — Leaders of five pro-trade organizations have published a joint op-ed in The Hill, a popular US political newspaper and website, questioning the US government's moves to escalate trade tensions with its leading trade partners.

Friday's article, titled "Why cripple the US economy with tariffs when it's hitting full stride?", was co-authored by Deirdre T. Flynn, Sandy Kennedy, Brian Kuehl, Nathan Nascimento and Matthew R. Shay, who respectively represent the North American Association of Food Equipment Manufacturers, the Retail Industry Leaders Association, Farmers for Free Trade, Freedom Partners Chamber and the National Retail Federation.

The op-ed cited four local manufactures' struggling situation as examples, showing that even before the announcement of new tariffs on $200 billion worth of imports from China, trade barriers already had dire consequences for American businesses, workers and consumers.

Due to the tariffs on steel and aluminum imposed earlier this year, Philadelphia-based Howard-McCray, which manufactures commercial refrigeration and display units, not only saw profit decline by 8 percent, but also will have to consider cost-cutting measures, such as layoffs, decreased benefits, deferred salary increases and reduced spending on research and development.

Brinly-Hardy Co, a 125-year-old Indiana-based lawn care accessories manufacturer, has laid off 75 employees, while Grandall Industries in Ohio postponed hiring at least 30 new workers. Vollrath Co in Wisconsin also stopped hiring in response to aluminum price increases.

Meanwhile, the op-ed indicated that farmers have been hit hard by retaliatory tariffs from China, the European Union, Mexico and Canada.

"Soybean prices have plummeted while dairy, beef and poultry inventories are piling up in warehouses across the country. The administration's farm assistance has done nothing to offset the potentially permanent damage to trade markets."

Moreover, the article said, "on top of fewer jobs for American workers and less income for farmers, families will find their budgets stretched as prices rise for everyday goods. We've already seen double-digit price increases for washing machines following tariffs imposed earlier this year."

"Soon, Americans will be paying more to furnish a new home or nursery, repair a car, own a pet, buy groceries or even purchase necessities like toilet paper. Shopping bills will be higher, and those costs will start to add up, erasing savings provided by tax reform," it warned.

Even though the US economy is roaring, the trade organizations leaders doubted the administration's purpose to continue the trade war.

"In the face of these positive indicators, the administration seems determined to snatch failure from the jaws of success by escalating its trade war with our top trading partners," they said, predicting this policy will not fulfill the wishes of its proponents to deal with unfair trade practices claimed by them but do more damage to US businesses, workers and consumers.

"We should be resolving these disputes through existing international trade agreements and organizations instead of inflicting harm on our own people," the op-ed concluded. "We ought to be eliminating all trade barriers and doing everything we can to keep the good times rolling for all Americans."
