You feel like this sort of liberal should be asked: how much is enough? When will we know that the government is spending enough on the safety net, or is your answer always that we need to spend more, no matter how much we're spending already? Does evidence on spending effectiveness even matter to you? The problem here is not that the US is spending too little on a safety net, it's that we don't get much effectiveness for what we do spend and we have all sorts of policies that work in the other direction to actively make things worse for the disadvantaged classes. Like the "war on drugs", the "war on terror", import protectionism, immigration restrictions, high minimum wages, and farming price supports - all issues where the libertarians are practically alone out there in trying to make things better. Here's a nice series of video shorts describing some of the issues where libertarian economist-types differ from everybody else: https://www.youtube.com/watch?v=-89qFWVrrmc https://www.youtube.com/watch?v=-89qFWVrrmc
