Student/teacher ratios have gone down, not up over the last few decades. This isn't a lack of funding.
Teachers are put in an impossible position with students who come from homes where the parents don't do their proper jobs. It's never been easier to be a neglectful parent. Your child will be entertained non-stop by an iPad and a video game system. They won't get bored and bother you. You can send them to their room and do whatever you want if you don't care if they are sleeping or not, as long as they are quiet.
The "iPad babies" are an epidemic in schools.

My sister is a K-12 educator in a poor, rural public school system in southeastern Virginia.
In recent years, she's seen a surge in students who are sorted, improperly, into special education classes. These are students that exhibit symptoms of various learning disabilities, but these symptoms heavily overlap with the symptoms of children who are sleep deprived and over stimulated by dopamine activating content on the devices they are addicted to.
Yes to this! So many people turn a blind eye to the critical role parents play in supporting teachers holding kids accountable. And I get it, holding kids accountable is very, very challenging, but that's the gig people sign up for when they decide to have a family.
And I'm a former high school teacher and my wife is a current high school teacher so I've experienced all of this first-hand.
The single variable that actually matters when it comes to school - and nothing else matters until this one is fulfilled: The quality of the peers who make up the student body.
Or put another way: The quality and involvement of the average parent.
A school can absorb an extremely small minority of "problematic" students if the rest of the student body is stellar, but that's about it.
There is not a single thing any public education system can do to counteract that simple fact. If the average student in the classroom is uninterested at best and troublemaking at worst, it doesn't matter how good the teachers are or what the ratios are, or if the classrooms are old and busted or brand new.
Until society becomes serious again, this problem will only get worse as education continues to be a political and culture war football. The best realistic thing I can think of is take a look at nearly all other western social democracies who have much better outcomes and immediately implement student academic tracking. But that would be politically impossible to do in the current state of the US.
I fear that things are going to get far worse before they get better. You could 10x the primary school education budget and likely continue to see worsening results.
When I went from private (poor) primary and middle school, to a rich suburban high school, to a poor inner city high school back in the 90's this was self evident. I didn't think it could get much worse than that, but the administrative and political classes figured out how to wildly beat even my exceedingly low expectations.
