Maybe y'all don't know - but YOU can buy American products  RIGHT NOW -  I don't know why this was ever even a talking point - cause you can - and always have been able to NOT buy imported goods. 

Ok -there are some things that you can't ... Avocados and Pineapples,,  some of that sorta stuff - I don't think there is an American product - and there are certainly other products that are not made .grown, etc in the USA  BUT you don't need to wait for Tariffs to "kick in" - you can buy AMERICAN - NOW - and you always have been able to.... ...

look you already know the price will be higher on an American made good  - ex. the Ford F150 - arguably the BEST pick up truck out there - with the Dodge RAM 1500 and the Chevy mid level trucks -  the F150 is American Made - and priced Higher then the other 2 but it's American ..  Mens shirts - American $30-$50 - made in the Dominican - $15-$20....  so Inspect the Labels - use Google , learn to  

There are things you will have hard time finding American made - Televisions, many electronics,, Phones, Steel, Many toys - aka Matell, Mens dress shirts, Most Silverware, Lightbulbs, ,
