I don't want my kid to be surrounded by screaming nigglets all day, but we're not wealthy enough to afford private institutions.
School is terrible because it is a one size fits all diktat, a prison for the fertile mind, a round peg being pushed through a square hole. A private school is a better school than a public school because the school can afford to give each child a bigger push, increasing the chances they make it through the hole... but it is still a school, you still end up with a square child.
The simplest way you can make school better for your kid, even when you haven't got a penny, is to give your kid the choice. Raise your kid to be interested and intrigued by the world, then give them agency. Let your kid go to school because they want what it is offering, let them take what they want from it and ignore the rest. If they decide that it sucks and isn't worth it, let them opt out, try again next year, try a new school, homeschool, unschool, whatever.
We go to work and sit in front of the bad screen lamenting our capitalist nightmare, and then we go home and stare at the good screen enjoying the fruits of our capitalist dream. The difference between enjoying something and hating it is being able to make the choice. I'll spend hours writing comments on the internet for free but god forbid I had to do this shit for work, I'd rather kill myself.
Homeschooling has a bad reputation because so often it isn't a decision made in service of nourishing the child's mind, it is a desperate parent's way to keep their child trapped in the parent's fiefdom If homeschooling is chosen based on the specific needs of a specific child, if it is chosen because it is the best available option to nourish that child's mind, then it is a great choice.
Anyway, what really matters, more than education, is raising your kid to be an optimist. Sure, the world is fucked, but don't weigh a kid down with that, let them believe that anything is possible, let them spend every day enthused about the future. Pessimism is far more dangerous than public school. Success comes from, like, 90% being able to ignore the depressing reality of life and 10% hard work / talent / intelligence / opportunities / privilege. There are a lot of successful idiots, but no successful pessimists.
All that assumes your roll of the dice produces a good kid, but guess what, the same lesson applies, nothing good comes from treating your kid like a dud, be an optimist, treat your kid like the world is their oyster, even if they're a furry.
