Then, please, enlighten us mere mortals with your infinite wisdom.
The tariffs are collected by US Customs as products pass from Mexico into America. The tariff, in this instance a Mexican Products tax, is paid by some American individual or company. Generally, the tariff paid by the importer is passed along to the individual end purchaser, the Guacamole eater in the avacado instance.
Since Americans are paying the tariff, there is no Mexican money involved. The tariff in no way obligates Mexico to pay anything into our economy especially not to build the wall.
If paid, the tariffs on Mexican imports come right out of American pockets.
The intent of the tariffs on Mexican products is to retard or end the import and purchase of Mexican products thus doing harm to the Mexican economy. The tariffs are scheduled to increase until the economic pain becomes so great that Mexico must either capitulate or die.
thus endeth the wisdom of bert on the subject of tariffs paying for the wall
