The topic is price fixing; the discussion is about the efficaciousness of price fixing. Why cap when they ought to have the power to look at the root problems? Why fix this one particular thing in a dangerous and probably-ultimately-ineffective way when they ought to be able to address the whole issue of price-gouging medicines more systematically? (Other than the possibility of this being a band-aid while they do that, but I wouldn't trust a politician's word on that even if they were promising it.)
