I found this podcast from this 
post:
I subbed today for a 7th and 8th grade teacher. I’m not exaggerating when I say at least 50% of the students were at a 2nd grade reading level. The students were to spend the class time filling out an “all about me” worksheet, what’s your name, favorite color, favorite food etc. I was asked 20 times today “what is this word?”. Movie. Excited. Trait. “How do I spell race car driver?”
I’ve only listened to one episode so far, but it’s really well produced, seems well-researched and very well put together.
From what I gather so far, the ways that the American public school system “teaches” kids how to read is not only completely wrong, but actually saddles them bad habits which fundamentally hinder their reading comprehension.
A huge swath of American adults are functionally illiterate, and I think I’m starting to understand why.
But then you’d have to elect one of the 30% of people who can read.
Not the case. I worked a while ago with a couple of comrades who weren’t able to comprehend the texts we had to tackle in our union work and what they do might interest you. They did speak with people about it and were often better informed than those who read the texts but thought they understood them.
you see that with foreign workers the ones who can speak english have outsised status and influence among the others
