video makes a good point, although I would argue that Hajj provides these people with the most valuable commodity of all, i.e. hope, to these miserable people,
Hope is ok and it is not absolutely valuable as we make it up to be.
When you make people hope for things they can not achieve, you will cause depression/misery. When you make people hope for things they can not achieve, as well as cost them resources, then not just you will make them miserable and depressed, but you will cost them resources as well.
Much better to have people set their hopes on sending their kids to get educated, or save their money to get a larger house. Or to buy a trcuk to drive around and make more money. As the person in the video said, to make this world a better place.
