From my personal observance, I have observed that such plans from government are successfully implemented to the lowest level. Those who own a BPL card also get benefited with whatever perks and special help is allotted to them. But the tricky part here is that 'Every person or family who has a BPL card is not poor. And every poor who is actually poor does not have a BPL card'.
While it sounds funny, but the real example to it is that one of the richest farmers in our town has taken the benefit from these plans and have added another two rooms to their house. As you enter these rooms, the interior designing and everything you see will shout it loud that they were not poor from any side or angle. In short, the share and rights of a needy, deserving family were snatched by a rich family. This was just one case, but sadly, there are many.
No matter who had been the ruling party, the plans of govt. have always seen several speed breakers and error in effective implementation. And then, whenever there is some scope of the plans properly reaching to the needy, such kind of people misuse them.
Despite of this, it is also a mistake from needy people who do not get their BPL cards prepared. Sometimes, the low cost food items which are sent by govt. for families below poverty line is grabbed by operators or middlemen and right when a real poor person comes to claim it, he is given next dates or a scolding full of insulting sentences.
