What are the reasons for poor education in England in the 19th century?

In 19th century England, in principle, there was no education, since only very rich people could afford it, they paid for individual teachers who taught their children. There were also schools, but they too were only available to those who could pay for them. Poor people who could not pay for their studies sent their children to work. At that time, child labor was very common, and since many ordinary people did not have enough money for food, they could not lose the earnings that their children brought them.
