'Speaking of swords......
Most everything in Mexico is imported. When things get peso expensive, stores simply can not buy inventory they cannot sell. Shelves get bare. I remember back to the sixties when "everything was cheap (according to pundits)"
Only thing was, "everything" consisted of about 2% of today's selection. Beans, tortillas, chili and salt. Packaged Flan. Macaroni so gummy you could form building bricks with it. Nido powdered milk. Even crummy grade margarine was scarce.
Beef so tough you had to grab the end sticking out of your mouth and yank to sever it. If you were unlucky it would snap back and give you a bloody lip.
You could stick around farming areas (culiacan, Morelia, Queretaro, San Cristobal and get fresh veggies reliably. Beach tiendas had wrinkled tomatoes, limp onions, chayote, cucumbers, and brown lettuce sometimes.
People remember 10 cent cola and 15 cent beer. Why do they fail to remember $2.50/hour USA wages? Or thirty cent a gallon Super Mexolina that burned holes in pistons?
