OK...
How does CostCo negatively impact economy? My city has one. Do you mean to tell me that CostCo is to blame for multiple shutdowns of pulp mills, or of small businesses not being able to pay their taxes? Note, if you will, that our CostCo is located a good half mile from anyone's home.
How does CostCo negatively impact enviroment? Is it because we use our cars to get there? We use our cars to putter around downtown. For many people, CostCo is closer than Downtown is. Is it because it clears out a large area? Our CostCo is in infill areas. (Built in a swamp) this CostCo in Vancouver is UNDERNEATH an apartment building. IMAGINE THAT!!! UNDERNEATH!
How does CostCo negatively impact culture? Did some sort of Culture-hating thing emerge from Hell and decide 'Hey, this looks like a nice culture! I'm going to put a CostCo here and fuck it all up!!!'? CostCo kinda came from our culture, didn't it? People were tired of having to go to 30 stores to get their weekly needs and wanted to spend more time with their family, so our culture devised a way to do just that - every store you need, in one store! Wow!
I'm all for local enterprise, but really, we only have ourselves, our culture, to blame for CostCo and Friends.
You can shop at Ma and Pa stores all you want, but you're barely accomplishing as much as Vegetarians are in their fight to make everyone stop 'hurting animals.'
