no, trump cannot lower prices  > "lower prices" caused the great depression  high prices cannot go back down without ruining the economy: businesses borrow on credit to buy their supplies and raw materials, and then re-pay those short term loans (net-30) as soon as sales are completed.  once inflation kicks in the business is borrowing at a higher price point and it cannot repay the loans prices drop, the result is immediate insolvency, bankruptcy, and economic depression. the best trump can do is keep prices from going up further, he cannot lower them back down.
