some people believe that the us should place controls on importa and products that compete with US businesses to prevent the exporting to american jobs

Answer

This is a bad belief because when stiff controls are put on goods that offer competition with U. S trades, many problems will occur such as hurting of the U. S exports.

Explanation

When tariffs are placed on imports, tariffs will have to be placed on export too. This will result into hurting citizens in the long-run. For example, in the Smoot-Hawley Tariff Act of 1930 where president Hoover raised protective tariffs on imports so as to protect American business, the process backfired a led to more depression because other countries also increased tariffs with affected U. S exports.
