Absolutely no doubt about it! Today's younger generations are traumatized by the over expectations by their parents and also the kind of mindless competitions seen everywhere!
Yes. Over expectation overburdens children and they need to overwork and suffer more if they do not come to parents' expectation. This is like overloading a donkey or making a horse run faster than capacity.
A few years back I woke up with horror while going through a report in the newspaper that a father hit his son in sheer rage as his young son was not able to execute a shot the way he wanted him to! And the son died on the spot!
