Remember, you won't get to have seven or eight young virgin wives until you are at least in your 50's. The Juicy young things are kept for the leaders. (partial joke, lighten up)
What hasn't been addressed here is the fact that the LDS church uses women as cattle, breeding stock. They are there to pleasure their man and breed. They also have to keep the house, take care of the children and sister wives if they are the junior wife, and be totally subserviant to anything the "master" says. A woman can not get into heaven without a husband.
Now that I have said so much negative, I will also add that many religions have their not so savory side. The LDS also are very self sufficient, family oriented, community driven and caring people. They do, however, intend to take over the world, and plan to do so in the market. Mariott Hotels, Beneficial Finance, and many, many more businesses are owned by the LDS church and it's holdings.
