Bullshit. Meat is by no means cheap. If you think meat is cheap you obviously have not purchased a joint of beef for a very long time.
Actually, at certain bargain markets, some meats are cheaper than veggies. It's mostly trash meats, like ground beef or packaged meats. The meats that aren't cheap are the grade-A quality cuts and specific animals.
At least, that's how it is where I live in America.
Also, meats can be substituted by a variety of protein-rich foodstuffs.
