Those prices seem overly dramatic. Avocados (certainly not native to the "few acres of snow" that is Canada) is 5 for ~$6 at the moment. Bread is sometimes $4 for a crunchy loaf I like, or maybe $1 in flour when I make my own.
I don't eat avocado toast, but it costs a lot less than what most people spend on decent coffee in a morning.
If you or anyone else is interested in bringing the price of avocados down, the state of Hawaii is currently funding (on a very small scale) avocado farming in Hawaii, which produces a non-Hass variety that is about two to four times the size, and has a slightly buttery taste, but when prepared with the standard ingredients, doesn't really differ all that much from the Hass except in color; it has a more yellowish tinge than green. But seriously, if anyone wants to beat the cartels at their own game, Hawaii is where it's at for avocado production.
I did put the term "organic" in there for good reason. Yes, I know that not everyone cares, but I was trying to go to the opposite end of the spectrum to the "50c" claim I was replying to.
