Ya, relationships like that always push on the desires of what parents think is best for the child. in terms of his brother he just ran off to do his own thing because it's his life and he can do whatever he want. It's interesting the way it's incorporated into the story though because Hachiken's parents are no different then the parents of the farmers who have their children grow up on the farm and overall have a high chance of being farmers themselves and taking up the family business when they grow older. It will be interesting to see how it plays out, since Hachiken himself seems to be pushing the ideals that even though they may come from a farming family and have a farming education doesn't mean that's what their life has to be all about, they should still have the freedom to choose what they want.
I imagine in the coming chapters Hachiken will find himself reflecting on the idea that he's being very selfish cause all he's thinking about is what he wants to do with his life, when his colleagues pretty much take responsibility in a sense for what their family wants out of them. Though then he may realize that there is a difference between pushing ones ideals and suggesting ones ideals. In a farming family it's only natural that hard labor would be part of daily life and a they would be well educated in what they do, but the parents themselves don't exactly push them to take the family business only give them the opportunity to while encouraging them to find what's best for them. Those kids however also find it as their duty to take care of the family business when their family can't because for everything their parents have done for them and to continue to be able to support them.
In Hachiken's case though his father seems to suffocate him more than anything, and his Mother attempts to bring out compassion in him, well I can't recall if he actually complimented the food, but she even though I think it was a lie, but she tried to shine a decent light on him so Hachiken would feel better about his dad. However it's that very lie that causes his heart to strain even more at their relationship because what he thought was actual encouragement and compassion/support for what he was doing was nothing more then a lie to ease his heart and allow him to feel better about himself without feeling as if his dad is judging his every action.
