I think it's more about ensuring that the system is structured in such a way that these things are minimized. If you don't want waste dumped in the river, ban it or tax it rather than subsidizing it. The Costco comparison is a bit apples to oranges, too. They have a substantially different customer base. There are a lot of people who can't afford that $110 membership. Lower income Americans are the ones who benefit the most from WalMart's services. Aldi is more competitive in this area, but they do it by significantly different means, and they're still focused on maintaining a very low labor cost, they just do it differently than WalMart does. And as someone who worked at WalMart for awhile, their lack of a union (Meijer and Kroger both required I have full weekend availability as a result of their union contract -- and I needed weekends free for my job at McDonald's) and the relative ease of being able to get a job there was a huge part in my own escape from poverty.
