I don't think being robin hood will end the poverty. you need to fix the system first. you must guarantee the contunity of equality. otherwise, there will always exist poorer and richer people.
we all don't have the same opportunities to be rich. there are economic, social and cultural differences. if we accept that we are all born with equal rights, we should have the same opportunities. but obviously we don't. that means rich people always steal from poor people already. because they are always born more lucky.
plus, to become rich, you need to steal from other people. for example, even if you earn a lot, you always pay your workers just a little amount. you need to hire more people for your business to be done, but you don't. then, your worker work harder and harder, but you pay him again the same amount or a little bit more.
there are more reasons, like personality... personality is also important to get a job. if you are not good at marketing yourself, you have more trouble with finding job.
there are also bigger economical-political issues , like capitalism itself makes some parts of the world poorer and doesn't let them to get richer.
anyway, i think we are all born with equal rights but don't have the same chances. that makes the world worse and worse. also, being robin hood will not solve the problems. we should first believe deeply that people are equal. but i know that it's a utopia. people are selfish inside their mind and soul.
