Anyone who studies the parsha sees that after these criticisms and remonstrances how Lavan repaid Ya'akov bad for good, the answer of Lavan does not address Ya'akov's severe complaints, and has nothing to do with them whatsover. However, it seems that there is a simple explanation. Lavan really does not give any answer. He is like anyone else who resists hearing the truth. He is stuck on his own interests, desires and the secret inclinations of his heart.
Some people run after improper gain, and some after other lusts.
They don't feel or imagine that they do not hear, that their minds are closed, that their hearts are blocked. These type of people hear only what they want to hear. Anything else goes in one ear and out the other. In every generation the tzadik has been oppressed, downtrodden and victimized by the wicked. While iniquity and injustice pile up to heaven, the heart of the wicked is expansive and untroubled.
