That's the Utopian dream of many. But the problems that people blame on "religion", I believe are more political problems and if, hypothetically speaking, religion removed from humanity in one fell swoop - or even over a period of generations, the same kinds of problems and issues will continue.. but then instead of saying "A world without religion is a better world", they'll be saying "A world without [some theoretical construct/methodology/whatever] will be a better world". No, I don't believe in Utopias. They make for good Science Fiction, but that's it.
