Answer: The protectionist business policies benefited industry but backfired by the end of the decade.
Explanation:
"Many of the policies intended to protect the United States from foreign imports had adverse effects. Tariffs placed on the import and export of foreign goods did not allow some countries the income needed to pay back their debts to the United States, which led to a loss of income. This prevented some American businesses from exporting goods out of the country, which also resulted in a loss of income." edmemtum
