More important than the drop out rate is that students who do graduate aren't educated enough to compete in a global economic system. The emphasis in public schools is on social issues, homosexuality, diversity, multiculturalism. Core subjects are being ignored because of class time limitations. The environment is not one of learning, but of passing. Easy subjects are discussed (not taught). There is grade inflation and social promotion. The graduating students will never be able to compete with students from around the world who really know something. Complicating this is that students want even EASIER subjects and resent actual education as discriminatory.
Well, I wouldn't go that far.
Sure, a little time is wasted on having the LGBT group give a little 45 minute presentation during "Multiculture Day," but for the most part, Math and Language Arts are taught.
But your point is: Is anything LEARNED?
We have been measuring "learning" for decades, and, without citing the overwhelming evidence, I'll go out on a limb and say that human capacity for learning hasn't changed one iota during the last 100,000 years, much less the past 50, despite whatever new teaching programs are implemented.
College graduates can barely read and can't do basic arithmetic without a calculator. The educational system is such a failure that some schools have given up trying to teach students to write. Block printing is good enough. It has to be. Too few can write their own names.
Making your way up the scholastic food chain, after you get past the social degrees in the History of the Chicano movement and Transgender discrimination studies, and move to post graduate science, math and design degrees the classes are dominated by Asians, Indians and a sprinkling of whites. There are fewer and fewer blacks and hispanics every year. If there are few admitted, even fewer graduate.
This comes down to money. Parents who want their children to succeed and achieve start early paying for private school or at the least, a supplemental school that will teach what public schools have long ago stopped teaching. Parents that make room in the budget for supplemental education will have children that can go on. Parents that don't get ill prepared graduates.
Worse, and perhaps worst of all, the students who do graduate with fluff diplomas and degrees are trying to enter the workforce with the same sense of entitlement that got them those diplomas and degrees in the first place.
