Basically he had an inferiority complex towards his brother for so long and we can see that theres a difference if we look at the father and uncle's present financial situation. The father had two sons and he vented his own inferiority complex to his own son who looks like his uncle and favored his son who looks like him

So the father hated the eldest son because it’s a copy of his older brother. Weird…
Anyway I’m glad it’s the present day now.
