My only chance for a normal life and education was public school.
A huge amount of americans are poor in time and money. The only option their children have is public school. Their future is entirely dependent on a public that is willing to invest in them so that they even have a future, one that isn't just "wage slave at walmart". Sure, it often doesn't work out, it's a struggling system that has been abused and ignored for decades, and it fails millions every year.
You know what doesn't help any of those millions of kids? All the wealthy families sending their kids to private schools or homeschooling and removing their property taxes from the public school system. Society will not be a better place for your kids if they are individually 10% better but 10% of the children born in the US basically have no access to education.
The advocation of "School choice" as conservatives are currently selling it is about taking away the chance I had at a middle class life. It's about saving a few thousand dollars for already privileged individuals at the expense of swathes of people like me who were at least average intelligence who had the audacity to be born to a poor mother.
If you think public schooling in america is deficient, then let us fix it.
