Kerala, with lower per capita income has a better human development ranking than Haryana. Hence, per capita income is not a useful criterion at all and should not be used to compare states. Do you agree?
One cannot completely conclude that comparing states based on Per Capita Income is wrong, but one can definitely say that the comparison of states based on only Per Capita Income is highly inadequate, as it does not clearly portray a right picture of the well-being of people living in that state.
