If by "meat" you mean "beef steak", then it's not usual to find such low prices but it's not that far off; ground beef does come out pretty cheap sometimes. But I include pork, poultry, and organ meats in the "meat" category, so, since you asked, I shop in New York City ...
Typically packaged dried beans are $1.50-$2.00 per pound; canned beans are typically $1 per 15 ounces.
Today one of the local supermarkets has "chicken livers" for $0.99/lb, "whole chicken" for $0.99/lb, "boneless chicken breasts" for $1.99/lb, "whole boneless pork loin" for $1.99/lb, "whole chicken legs" for $0.99/lb, "beef liver" for $2.29/lb.
I'd say that relative to dried beans at $1.50/lb, the prices for "fresh meat" are surprisingly low.
Milk can be purchased for around $2.50/half-gallon while soy milk ranges from $3/half-gallon to $5/half-gallon.
This is all in large part due to the inhumane "factory farm" treatment of dairy cows who are kept virtually immobile and dosed with hormones (rBST/rBGH) that make them produce about 1.5 times the normal amount of milk; this also results in painful mastitis and foot problems for the cows but increased profits for the factory farms. Feedlot cattle "ranches" yield cheap beef. Tightly packed coops filled with chickens whose beaks have been burned off yield cheap eggs.
Well, you asked :-)
