Oh, yea of little faith. Christ told us that the poor will always be amongst us.
Why would you object to the conception of a soul that has a chance to get to Heaven, whether or not the child was born into a poor family or a wealthy family?
Were the Blessed Mother and St Joseph poor or wealthy?
Eliminate poverty? Will never happen. But to subsidize or encourage it is not moral or ethical.
Reducing poverty however can be achieved. Free vasectomies and $100 to all who take the offer would eliminate a great deal of misery.
As for encouraging the creation of souls just so they have chance of going to heaven or Hell. That’s not only silly but borders on pernicious.
What is needed is an honestly Christian belief system, that can make good use of God’s grace to transcend poverty. But if someone won’t believe it’s there, he or she can’t use it.
