Yes of course "buy American.......it really helps keep our Mexican businesses in business"
That term "buy American" went out a long time ago. Almost everything you consume up there comes from somewhere else. America consumes 25% of the worlds production, yet it's population is 3% of the world.......it may not make you think, but it makes me think.
When a person rents a condo in Mexico....chances are he is renting from an American or a Canadian since they are big investors in Mexico, so then are you buying American when your travel south of the border?......aah me thinks yes!. When you rent you 20 buck a night spot on the beach in Mexico for your RV (components from Mexico)do you help America?....Yes on that one too, since Mexicans purchase so much from the US in the form of goods that it may blow your mind. The money they use to purchase your goods comes from you spending money here. If you think that you can have an economy solely based on your particular geographic proximity or your particular country ( I suggest build a wall and only purchase what you produce) without regard for the world around you, then it is you who should reconsider your thoughts, simply ridiculous thinking. Buy American, Buy Mexican, Buy Canadian, buy world view and quit being so myopic in your thinking.
