Obviously, as long as population growth outstrips our ability to reduce poverty among the working poor and the unemployed the total number of low income people will continue to grow. It's an absolute fact that dependence upon food banks, particularly by the working poor, has increased a great deal of late, around these parts at least.
While I consider that, on one hand, a disgusting off-loading of federal and provincial responsibility for their welfare onto charitable organizations, it is, on the other hand, a sign that more and more people are falling below the poverty line. I have yet to see any data which shows this can be accounted for by population growth alone, but it's reasonable to suspect it is not without evidence to the contrary.
I know this tactic sucks in stupid people and sometimes that's kind of fun but it's getting a little tired at this point in this particular thread, IMHO.
