You really live in a sheltered bubble and share the views of Americans and Mexicans that the left does, it isn’t even close to reality.
The views I expressed have nothing to do with leftist thought. THey are based on in person observation in the areas I am familiar with. I’m sure that there are other areas where what you describe is also true. Reality is different in different places. Have there been the kinds of education changes in the areas you know like the ones I have seen over the years in the areas I know? What is the status of trades education in the public schools you know, do the schools you know still have daily phys ed classes?
