“That’s not a conservative opinion...”
Oh but it is a conservative opinion. It is the opinion that your private property, and your liberty belong to you, and any gift you make to others must be voluntary.
Note that this does not apply to all poor, only the poor that are receiving welfare. Welfare as it stands, is theft. This opinion is that individuals and groups who want assistance could get that assistance by making a voluntary contract to trade reproductive opportunities for money. Nearly every person I know does this. They chose to have fewer children because children are expensive to raise. It is not an awful thing, it is commonplace. What should not be commonplace is stealing to pay for your children, but that, an awful thing, sadly is accepted.
This opinion is that people and families have authority over themselves, and that they have responsibility for themselves.
My opinions are modeled somewhat after Bastiat, Galton, Malthus, and others.
I won’t say who I think your opinions are modeled after.
Forced sterilization is not a conservative ideal. It is a totalitarian tenet.
