Economics is a positive science, not a normative one. It doesn’t tell what our values should or should not be, but merely what the cost and the tradeoff of anything we do. It asks why things are the way they are - not what they should be like.
So obviously, when an honest economist ever opposed a particular plan intended for social welfare, it was only because the said plan would hurt the very interests of the values for which that plan was set up. Economists opposed New York rent control, only because it deprived people of housing, which was precisely what this policy meant to avoid. Not because there are economic ideas that are based on allowing people to be homeless who can’t afford apartments.
So if anybody goes into the territory of suggesting which values are right and which are not, it’s politics and not economics.
There are people who have advocated that the state should have exhaustive functions, and that the state does not have and should not have obligations to provide programs for social provisions like education. These ideas have basis in politics. Obviously, an economist can point out the costs and inefficiencies of public education, but if a person has the idea that children don’t have any fundamental right to be educated by the state, he has no need to see the economist’s facts, because the economist’s facts are only useful for seeing whether the state can serve children better through private or public education, not for seeing whether the state has any obligation to do so.
So anyway - while a lot of us may support free market and government non-intervention in commercial activities for economic reasons (for judging costs and benefits to society), the political position of such people still may be inclined towards social justice. They still might choose welfare programs, knowing full well that it will involve a cost for the rest of society, and that the benefits for the rest of society will not be greater than those costs.
So do you support social justice? Do you feel the government should help and uplift the poor, and create programs for social development? Or do you go by the doctrine of natural human rights - which says that people have the right to pursue opportunities for their wellbeing, but not the right to be given those opportunities by the state?
To be honest, I can’t give a specific answer. I know I wouldn’t like children to starve to death, but I know wouldn’t like government programs that still largely don’t stop that from happening either.
