But these redistributive taxes are what @KevinCarson1 calls “secondary interventions”:
“Secondary interventions include regulatory and welfare state measures that constrain those privileged actors from abusing their privilege in ways that undermine the long-term stability of the system. Such secondary interventions are intended to prevent, among other things, levels of destitution, homelessness and starvation that might destabilize the political system. They serve to make the system of privilege at least minimally endurable on a human level.”
That is, we miss the majority of the picture when we focus only on the redistributive welfare role of the state and not its predatory redistributive functions: violently establishing and policing private property, creating and awarding monopolies, creating artificial scarcities, suppressing labor organizing, imposing taxes on workers, etc.
Abolishing secondary interventions without first addressing those primary interventions—which is precisely what right-libertarians want—would absolutely make life worse for workers. But those secondary interventions are made necessary by those primary interventions, and, critically, they are funded by the workers who benefit from them.
Welfare is not free money from the rich, who are rich only because they have already stolen from the working class.
