That's a great point. I can get a can of black beans for $0.50 (and dried black beans for even cheaper). I can get a chicken breast for ~$2. The black beans still net 98g of protein. But I also get an additional 500 calories more than the chicken beast. And that's with the subsidies for poultry. I'm also going to pre-empt the "not a complete protein source" argument with the fact that we're talking about a healthy diet and no one is eating only beans or only chicken in their diet. Plant proteins are always going to win in terms of cost efficiency over meat. There is always going to be a cost for the increased protein density of meat.
