Probably in developed countries, trying hard might be an option where in poverty means you most likely have cell phone, laptop and roof over your head. But in developing countries like India, where abject poverty its ugly head, the people even are not aware that there are opportunities which could enable them to move up. All they have time and energy to think about is how to get the next piece of meal for their family. This also partly due to social structure which is deliberately designed to keep them that way for the benefit of upper class people.
