How tariffs are breaking the manufacturing industries Trump says he wants to protect

President Donald Trump 's trade war has illustrated the folly of central planning, says Julian Zelizer .

Zelizer: Tariffs create higher prices for inputs, which in turn can reduce sales for manufacturers' output.

He says it's not the president's job to set prices or decide what can be bought and sold.

Trump will fail as the country's department store manager in chief, Zelizer says.

The day the "reciprocal" tariffs were meant to take effect, one week after they were first announced, Trump suddenly announced a three-month pause in implementation.

International trade is essential to American manufacturers like Plattco , whose industrial airlock valves are used by other blue-collar industries, such as mining and shipping operations.

David Rothkopf : Manufacturers expect to see fewer orders, longer delivery times, declining inventories, lower employment.

He says they're worried about the inflationary impact of tariffs, which they say will inflate prices.

Trump 's tariffs will increase American manufacturers' costs by 5 percent to 15 percent , Goldman Sachs study found.

The president is not guiding a rebirth of American industry, he is overseeing a ritual sacrifice to false god of central planning.
