 Buchanan and Friedman are less focused on rejecting social justice, but their positions resemble Hayek’s. Buchanan’s contractarianism leads him to hold that a society’s distributions are fair if they are the product of rules that all agree to, and otherwise not, so if pursuing distributive justice means breaking the constitutional rules that we have agreed to, it is problematic. But social contracts may have redistributive rules. If people agree to redistributive rules, then redistribution is justified. In this way, Buchanan is closer to Rawls than Hayek is.
