Go outside of the Western world to Latin America, the Philippines, Africa. The Catholics remain faithful and families are blessed to have a lot of children.
The United States is a whole different world. Mother Teresa implied that the United States had the most poverty in the world - poverty in the sense that it had lost its moral and spiritual fiber.
The Church will not lose as many members as you think in the scenario that you suggested. I know that members of the Latino Catholic community in the United States do not hold it against the Church if they are not allowed to partake in the Eucharist because of divorce. There is no reason to be angry at the Church. You can just try harder to live a better life.
God Bless the Catholic Church!
