They do mark certain product as "Made in USA" now. Why not extend to every origin?
And can Amazon gaurantee that tariff cost of each product is correctly calculated? Is it even possible? LOL...
Some people just want to sabotage Trump for the benefit of their party. It is very easy for finger pointing. It is very hard to try to do something.
It is not like that every thing Trump did are the right things. Some of them might be very wrong. But to advise him that what he did is wrong is quite different than hoping that he would fail.
