We can't say when and where it all began, and it's inevitable, and we have to live with poverty as an infinite part of the world. Like in a seesaw, if one goes up, the other comes down automatically, and if one becomes affluent and the one less possessed comes down the line of equality. Though we can't consider it as poverty, this could be stepping down the process to push one to the poverty line. The reason for poverty could be plenty, and I'm not complaining or protesting that none should become affluent, but all wealth stored under particular leaderships denies the right of people in need.
I think poverty cannot eradicate as long as there are more and more ups and downs in society. In the way, rich become richer, poverty advances to a stage of the same. So, the thing that needs to change is to create more opportunities for the poor to lift themselves the way they needed. And either poverty is removed or not, we need to make sure that no one dies of starvation.
