There's really no way for liberals to win with this one because their wealth is predicated on rising property values—which naturally produces homeless people. If you even adopt the milquetoast liberal approach of constructing affordable housing, that lowers property values. If you just pretend the homeless people aren't there, that lowers property values. So as a liberal, there's really nothing you can do. Capitalism has fucked the planet for the last couple of centuries; now this monster, in its vicious hunger for ever-dwindling sources of profit, is finally coming for you, too. The death camp approach is also pointless (purely from an economic perspective) because rising property values will continue to produce homeless people, which will mean more tax money for death camps, which themselves will produce ever-larger numbers of radicalized people who will increasingly adopt violent and organized methods to oppose you, etc. The only way to deal with "the homeless problem" (actually the landlord problem) is to eliminate landlords and establish quality universal housing—which means that dwellings cease to be an investment and you, Mr. Liberal, have to actually get a real job and work for a change.
