Too bad this is getting so politicized.  It is true that so-called 'ethical' (organic, locally sourced, etc.) food is more expensive.  I was one of a family of six, and there's no way that my parents could have afforded, on their low-to-middle middleclass income, to feed us with organic milk, eggs or meat (the veggies would have been a little easier).  To be honest, it wasn't one of their priorities either.

I do prefer purchasing the better quality food. It tastes better (especially if locally sourced, as well as organically or naturally raised meats).  I can't help but feel that there's an extra health kick eating food that likely has fewer pesticides sprayed on it or anibiotics or hormones fed to it. 

Is there some marketing gabble? Yep there is - but that's not all it is either.

If you're not well off, you can approach this as a priority - I do.  Many who say they can't afford this can afford a whole host of purchases I wouldn't make.
