Yeah I think it's crap when people say they "can no longer afford" a vegetarian diet, as my boss recently told me her daughter said.
I was like, no. Total crap.
If you live solely on fake meats or shop only at pricey, small health food stores, maybe.
But I only buy a few "special" items a week - Boca burgers, fake chicken nuggets, whatever.
A box of Boca burgers, which I think contains 4 patties, costs $3.50 or $4 here, tops.
That's less than $1 per patty. Add maybe another dollar for a nice wheat hamburger bun, couple pickles, lettuce, tomato and onion (or whatever veggies you put on a burger).
That's a meal for under $2 in most cases.
You can eat a healthy, vegetarian meal for about the same amount you can eat meat, it just takes a little planning.
If I lived off of Kraft mac&cheese and the $1 menu at MacDonalds, like I know some omnis do, I could probably eat for super cheap. But I'd feel like crap!
