Blame neither the position nor the individual. If you identify the fault, try to remove it. And removing those faults is what we are doing here through meditation and practices.
If people do these practices before getting into power, it is good. And if they do them after assuming power that also is good, so that they remain balanced.
Balance the mind, since all negativity arises in the mind and spreads from there. There is no sense in blaming the seat. Through awareness every position of authority can be managed properly.
