Raised as a Mormon, there was often LDS paraphernalia on the walls.
One I remember was a map of the world showing the location of all the Mormon temples in the world.
According to their own page there is 129 operating temples. Then there's also thousands of churches, over 50,000 missionaries across the world, and over 300,000 high school students enrolled in seminary (the special Mormon way of sneaking church into school).
Now, I do know that, as is with most churches, they do donate money toward good things but...imagine if they had not spent all that money on 129 of these:
And instead spent that money on helping the world. Why do we need 129 of these across the world for them to do their archaic rituals of magical marriages and post-death baptisms. That's a lot of money for such useless actions.
Of course, I'm not saying they're the only church that spends money wrong (and they're not even the worst), but they're the one I'm familiar with. Being that they're newer then most of the other big ones, they're perfect proof that we won't be seeing a religion that works toward helping people. They will always work toward helping themselves.
