The fact that Lavan wanted to destroy his own children and grandchildren does not make any sense and goes against human nature, even for someone like the lowly Lavan.
We can understand this by looking at the current times. Lavan represents a “worldly man” with a worldly (secular) outlook. He wanted his children to receive an education based on worldly attitudes (הנחות העולם). Yaakov wanted his children's education to be according to Torah. This is also seen in Yaakov’s dream when he saw the ladder from the ground reaching to the sky – the idea of uniting the coarse physicality with the highest spiritual. On the other hand, Lavan wanted to uproot everything, by trying to only have a worldly education.
Chinuch according to Torah is the foundation everything. Education only with worldly attitudes destroys everything. Pharaoh wanted only to attack the males, representing his opposition to holy intellect. But Lavan wanted to destroy everything through educating the Jewish youth with worldly attitudes.
Some argue that we need both Torah and Derech Eretz, referring to education in worldly matters... The truth is even the statement of the sages itself implies that Torah should be the primary focus, and the Derech Eretz merely secondary.
The only way to truly recognise how the “Chinuch approach” of Lavan destroys everything, even for someone who learns the revealed teachings of the Torah, is through learning Pnimiyus HaTorah (Chassidus) and bringing it into their study of Niglah. This is what it means Tzai U’lemad; Lemad refers to learning only Niglah. Tzai U’lemad means to bring the Pnimiyus HaTorah into the learning of Niglah. Then you will sense how “Lavan” wanted to uproot everything.
