Market-liberal economists argue that heavily subsidized, single-payer systems suffer from chronic allocative inefficiencies and supply-side constraints. By suppressing price signals, tax-funded models inevitably lead to non-price rationing, manifesting as prolonged wait times for non-urgent treatments and restricted access to cutting-edge medical technologies. They advocate for hybrid models that introduce targeted private competition, co-payments, and supplemental insurance to incentivize consumer responsibility and stimulate clinical innovation.
