Wow, there is so much to disagree with in this dreadful vegetarian-bashing piece but suffice it to say it is the whole underlying cynicism that is most disagreeable.  

"There are no social benefits to consuming ethical animal flesh." What nonsense. This statement just kind of hangs there, unrelated to the rest of the text. 

Musing on how price and ethics relate is pretty much a pointless waste of time. Since when did anyone ever think they were related, except indirectly and collaterally? 

The health benefits of eating less meat, or eating no meat, are many, and many people are doing just that. It has nothing to do with price.

Add to that the true ethics of eating less meat, or eating no meat, which have nothing to do with price, but more to do with spirituality and the ethics of consuming less and better, and reducing suffering.
