I did a lot of what I guess would be called charity work down in Mexico back in the late 70’s and early 80’s.
I would purchase what our school district up here would call surplus or obsolete materials and truck it down there to reinstall in rural schools.
Student desks, light fixtures, paint, plumbing fixtures, black boards, boxes of pencils, reams of older style copy paper, any thing that the district considered obsolete or too old fashioned.
The bureaucrats, politicians, and state or federal agencies I had to deal with were a bunch of greedy, corrupt , pains in the ass.
The kids, their parents and the local shop keepers were pretty good people, the others not so much.
The kids and parents would pitch in to help with the remodels, the local shopkeepers spoke better english than some of the guys who worked with me here in the states, and were very helpful in tracking down all the parts and pieces you need to do a retrofit remodel project.
DO NOT DEAL DIRECTLY WITH THE RURAL SCHOOL PRINCIPALS, THEY ARE A BUNCH OF THIEVES AND CROOKS.
These projects were out of my own pocket (I was not a rich man by any measure), the graft finally got so bad I had to just say to hell with it and stop.
God Bless you for all that you did for those children. I’m sure it enriched their lives and helped them get a better education. The corruption seems to be at the heart of their problems.
