This country DOES NOT speak the same language state to state on most topics - education chief among them. The concept of "education" means something completely different in Mississippi versus California, for instance.
There has been a slow motion systematic dismantling of public education in "red states" and things like the increasing prevalence of religious influence on our laws and education infrastructure. These things severely impact the quantity and quality of teaching resources. Republicans want undereducated, easily-frightened and broken people to grow up to not vote, or to vote to perpetuate the status quo that they know (an objectively broken system).
Charter schools are funded by vouchers. At first, you'd have options for multiple schools in most places, then the vouchers would cover less and less each year with you spending more and more out of pocket. Then, religious schools would in turn lower their tuitions (as they can afford to subsidize if it means indoctrinating new kids). The result is that families with less money would go with whatever the voucher covers, which would only be religious schools in more and more areas with tone. That's the plan.
Louisiana is CONSTANTLY at the bottom of the nation in terms of their education offerings. Here's one of those lists: https://www.newsweek.com/most-least-educated-states-america-ranked-1583019. These are craven theocratic fascists and they won't rest until public education is eliminated.
