You are exactly right at your opinion. All these political meetings and rallies are nothing but a wastage of money and time. The money spend on arranging these rallies is a huge one. This money and time if the political party leaders spend for the welfare of the poor people then it would have been highly helpful for our economy.
Again, as you said most of us are now aware of the right or wrong and these rallies does nothing instead of influencing people towards the wrong. The political leaders are allocated to a specific job by the countrymen. So it is indirectly we, who appoint them. So they should do that job only for which they had been selected or appointed instead of organizing meetings and rallies.
One more thing to add up the meetings and rallies are mostly included with violence and using abusive words against the opponent so these should be banned for a peaceful country and maintaining the political stability of our country.
