Talk about a goalpost shift!!!!
So the link in your post goes to a chart that shows education spending "skyrocketed" in the 1960's and 70's, and then it was cut beginning around 1980 and did reach the 70's levels until 2002. Then, according to the chart you linked to but didn't read, education spending was cut AGAIN in 2010-11, and it skyrocketed in 2020 because of the pandemic. But did you happen to note that it dropped to levels below the peak in the 1970's? No, because you didn't even look at the link. You posted it compulsively because of how insecure you are.
Again, this is all info on the chart in your link, you hack.
