Alright, I can't copy the jpeg, so I'll recreate what it says.
HOW CAN A POPULATION BE CONVINCED THAT A LIE IS THE TRUTH?
21% of Americans are illiterate.
54% of Americans can't read beyond the level of an 11 year old.
57% of Americans have no education past high school.
America ranks 36th in the world for literacy levels.
White US-Born adults are the largest group with low literacy.
This is a graphic posted by my high school band teacher. He had a lengthy career and I've been able to maintain a friendship with him to this day. He is politically extremely left, and very vocal about his politics on social media. Most of the people he interacts with echo his positions.
I suspect that he posted this graphic to own someone, without realizing the message it was sending. Assuming these numbers are correct, and most of what I've seen makes this look less somewhat better, then there is a glaringly obvious series of questions to ask.
What federal department could have some responsibility for these dismal numbers?
What union also might have some responsibility here?
What profession might have some responsibility here?
What political party are teachers unions most closely affiliated with?
What political party controls the majority of urban areas with poorly performing schools?
Now the 57% have no education past high school is interesting. Especially when you consider how many billionaires/successful people don't have an education beyond high school. Also considering that is is totally possible to have a high earning potential without a college degree.
Of course, the spin is that people without college degrees aren't very intelligent. Yet, we see plenty of evidence that the education industrial complex is happy to take students who's test scores indicate a likelihood that they won't succeed in college and can't afford college and saddle them with loans that they have to repay even though they didn't do well in college. There is a sense of credentialsim on the left that prizes the credential of the degree above all else.
As for the last point, US born whites are (for now) the largest demographic group in the US. This is a situation where it'd be nice to look at the per capita breakdown of the raw numbers as a way to determine what this "statistic" really means. If that raw number is in line with the per capita/percentage then it means nothing. If not, then we can talk.
Personally I don't think I'd be touting the failure of the education system, and my political party, if I was a retired teacher
