Hope isn't deluding yourself that there are no problems in the world. Hope is believing that the world can be changed for the better.
The first step to fixing a problem is admitting there's a problem. Once you understand the problem you can then work on solutions to those problems.
I think you have "hope" confused with delusion and apathy. You can go ahead and hope and pray that things will improve and leave it up to the adults to actually improve things for you. Making real positive change involves taking a cold hard look at reality. If you're unwilling to understand reality then you're incapable of making any positive change.
