How does Finland do it? Copy them as much as possible, since it's clearly working. Gaps in Finlands system? Pay experts to figure it out. I don't claim to be an expert - you don't need to be, to see how bad the current system is.
If we can afford $20 trillion on interest payments for illegal wars on the other side of the planet, we can figure out how to fund schools.
Not sure what you mean by "specific blaming and accusations" - there are real forces fighting back against educating children in a safe and happy environment.
They're not even that sneaky about it. Pretending that extremely well funded and organised and power groups are not, for example, banning books, abortion, cutting school funds, cancelling school lunch programs, giving millions in TANF funds to dried out quarterbacks, etc, etc, is like ignoring the termites eating away at the foundations of your house while spending all your money on grenades to protect from home invaders.
