This argument is being brought up every time someone talks about any (especially environmental) fix that would cost money. By now I believe there is a certain part of the political spectrum in the US who need the poor just to make these arguments, because otherwise maybe someone would've done something about the issue. Ironically the ones who shout loudest about the poor people who can't afford these measures, are also the ones with the strongest resistance to fixing the huge economic disparities in the US.
