One major reason we depend on centralized schooling systems. Charter schools, public schools, private schools etc. is because the vast majority of parents can't afford the time or the resources to educate their own children.
Beginning in the early 1900's men began working more and more jobs in factories and businesses because of the boom in industrialization. But even though dad wasn't at home. children still had mom, aunts, uncles, grandparents and other family members to support and help nurture them. By the late 1940's the so called "nuclear family" came to be the apparent norm which actually shrank the amount of contact kids had with different family members.
Despite this most fathers and some mothers still made more than enough money to support the family and spend time with the kids. But the quality time together still decreased nonetheless. By the 1970's women were "encouraged" to work outside the home, earn their own money, divorce their husbands, throw their children into daycare and become a functioning TAXPAYERS! Yaay freedom. :-/
Add onto it that the social welfare programs boomed in the 1960's and 1970's and many of the social programs targeted black women demanding that they provide valid proof that they DON'T have a man in the house. Now children, black children in particular really didn't have anyone to spend time with them during the day. Ever since then this cycle has continued up to the current generation.
In every instance of the family shrinking and dividing. Centralized schooling took more and more of the space where parents and family were supposed to reside.
Another reason is quite simple. Inflation! The Federal Reserve is allowed to print more Federal Reserve Notes. Big banks are "Too big to Fail", The federal Government can give them money instead of letting them go under like small businesses do, This causes many corporations to move overseas and creates an environment where less people have employment and the fact that in 1971 The Nixon Administration removed the United States from the Gold standard.
All this both Devalued the dollar. As in every dollar in the year 2000 could purchase only a fraction of what that same dollar could have purchased in 1970. And more people don't have as much income since they're unemployed. So you have a population that has less money that's also losing purchasing power. In other words an increasing LOWER CLASS that can't afford to educate their children. So they rely of the easiest alternative. Centralized schooling(vast majority public schools)
Because the currency is devalued. The people that do still have a job have to work more than one job just to cover the rent for a tiny apartment building in a not so nice neighborhood. Again devalued money. If they were to work only one job and try to spend time with their children. They would either get evicted eventually or they would have to rely on more government handouts. Then it has to be factored in that the ones who do work more than one job are too stressed, tired and in physical/emotional pain to do any type of activity with their own children. Children on a subconscious, ancient, archaic level DON'T CARE. They need some type of socialization, comfort, love, interaction with someone that cares about them. So what can parents do? What is their only option?
They have really no choice but to dump their kids into public school and allow them to socialize with phones, screens, machines and other mentally damaged and emotionally neglected children.
Last but not least is single mothers. Single mothers are under even more stress to socialize with their children. Especially their sons. But whether they chose this life or not. The odds are stacked even more heavily against their ability to really raise their off spring. So they're even more likely to relinquish the education of their child to the only entity that is there. School. Mostly centralized and tax payer funded school. Public school!
Other options are more expensive! : Public schools have by far the highest convenience.(isn't it sad that the education of a child has been relinquished to our conveniences?) We pay only through our tax money instead of up front. So we don't feel the pinch of having to educate the next generation.(funny how parents want their kids to be responsible but don't take DIRECT responsibility for their child's education. and they do this in droves)
Private schools are of course expensive and basically a rip off. They get roughly the same incorrect education, the same indoctrination, the same authoritarian mentality from their teachers(of whom they didn't choose) and have a little bit of useless wasteful religious indoctrination mixed in. The only positive thing that can be said about private schools is they appear to much safer than public schools by comparison. Is that worth $4,000 to $8,000 dollars a year though? :-/
Unfortunately as ideal as homeschooling would be. In the modern era of 50% to 70% of people live with mom, divorce is still around 55%, nearly 50 million people on food stamps, most adults male or female ARE working two jobs to pay off all expenses,(gas, electricity, water, food, clothing etc.) the dollar can't buy as much of these utilities as they used to and over stressed tired and unhealthy parents. Home schooling WILL NOT work for most modern families. Unless a huge and drastic change comes over society and soon.
