I haven't seen any evidence that giving more money to academia improves student results. It certainly hasn't worked for colleges, where you've seen a negative correlation over many years between quality of education and funding.
"Fewer students per teacher" is widely supported by research, and teachers do cost money.
But obviously just blindly throwing money won't help.
All anyone ever talks about is "blindly throwing money". That's what the original complaint I responded to was; This is because we didn't sacrifice enough money to the altar of public schools! If it was just about classroom size, it wouldn't have warranted a response.
Well then you haven't been looking very hard. If you look at PISA results (essentially the best data we have on this so far) there is a strong correlation between investment into education and performance.
