You are only going to get out of education what you want to get out of it, no matter where it is. The main reason private education is better than public is because most of the parents who put their kids in private school give a shit about their kids' educations. This means there are less classmates that have been taught to spurn education from a young age. That factor alone can lead to much worse results even with all else being equal.
And they've got the $$$ to pay for it.

Sounds like public school, going there actually makes you dumber, no joke.
Yup, public school.
And I've never been in or near a private school, so I've got no reference point myself. (Take that as you will.

)
I was plopped into the gifted program sometime in elementary school. Upon later reflection, that was more like, "We don't know what to do with you, so go here to this room instead." But, it
was nice to occasionally get out of class for it, and not have to be bored to death for.....well, various reasons.
Americans were once wild, feral animals who would never be caged. Well we've had generations of the cage being closed in around us. "God and Guns" are a symptom to illustrate the disease, do not confuse either for being the disease.
So what ails us? Society. Government and comfortable living. We've grown fat, lazy, and indifferent towards our fellow man. There are so many of us, who cares about one more person, about each other? They are competitors to take my government handouts - nothing more than a threat against my survival in this cage we share.
Gone are the days of a difficult life where you were dependent on the people next to you. Your neighbors were your life, a strong communion. Today it is your government. The neighborly bonds have been severed and instead of our natural instincts, instead of depending on one another we freely seek to dispose of one another.
It's all a spectrum, at least as far as "fat and lazy" goes. I've never had to run down an animal and kill it with little more than some spears or poisoned darts, and then skin and gut it with some sharp rocks.
We're domesticated primates now, though many of us stubbornly refuse to acknowledge that ancestry.
And unfortunately, our instincts didn't anticipate an environment like this. You do indeed still have many ancient tendencies and behaviors present. In times long past, hoarding resources could likely be what allowed you to
live at all. Now, there's food everywhere, at least in the first world. Go to a grocery store. Thousands of square feet of food that's just sitting there, much of it capable of being stored for months or years without degradation. Clean water comes out of pipes with a simple touch of a knob. Strong shelters also afford us light, even at night.
Our instincts would call this a utopian paradise, if they could make sense of it. But they're still geared to assume that death is waiting around the next dark corner.
Tribalism was a curse, but instead of shedding ourselves from it - we've merely adapted such instincts to fit our cage. These days each man stands an island. We have destroyed ourselves by usurping the brotherly bonds that made us great.
"United we stand."
It turns out that the usage of "we" in that statement is in an extremely exclusive sense.
