It will take time for the market to adjust (if the tarrif stays). Over time it will 1) raise the value of US dollar, making all imports cheaper, and b) drive production here, making more US jobs. and c) the importers / sellers may absorb some of the tariff, or risk losing sales - either lower purchases or loss to other countries who are not under tariff.
There is always a pain period. There is no free lunch.
Still, raising prices for goods on a shelf at retail today that came in pre- tariff is simple price gouging.
Don't believe everything the talking heads tell you.
