How does that work without your favorite hole-in-the-wall restraunt closing down because almost no one wants to pay $50 more for a bowl of ramen noodles every week?
You are already contributing to someone's near poverty living if you pay taxes. See social security and unemployment insurance as examples.
For places like these, it's the market's demand for cheap ramen (or whatever) that means the difference between someone living at poverty level and having no livleyhood at all.
