the biggest problem with non-meat foods (for me) has always been with their macros. I can get 32g of protein with nearly zero fat or carbs from 4oz of chicken for less than $2 a serving. Last I checked, this was not possible with alternative food.
The company Tyson invested in stacks up quite well to conventional meat. http://beyondmeat.com/

His top-line number is that a $5 burger would cost $13 without various subsidies, funded by $38B or year in subsidies to the meat industry.
I also found claims that removing subsidies would eventually lower prices by allowing competition from countries without subsidies. But my guess is there's a limit to bottom price globally given current tech, regulations, tariffs, and land availability. And it's difficult to know where that is relative to subsidizes process in the US...
The purported subsidies of $38 billion per year divided by the 50 billion burgers per year that everyone seems to think Americans eat (including this author) is less than $1 per burger.
(But the $38 billion/year is wrong too ...)
2. Unless you're on a very specific diet or have some kind of exercise heavy hobby, that is a lot of protein (essentially a day's worth).
I have a lot of hope for lab-grown meat, but there's still a lot of progress to be made for meat analogues.
