ELI5: Why are rabbits not a preferred source of meat, seeing as they breed so easily, and are so easy to keep?

Rabbits breed, well, like rabbits. They are easily tamed and don't take up much space. Why is the rabbit meat industry not bigger? 

Wouldn't it be better to breed rabbits rather than cows (from a methane/global warming point of view)?

Rabbit consumption is higher in Europe than it is in the Americas.

Rabbits are relatively useless farm animals and were not a significant part of American agricultural life. Chickens provide an ongoing protein source in eggs, pigs can live largely off of waste products. Cows provide milk and meat cows are relatively low maintenance on low-quality land. This created cultural associations with these animals and their products which compete with rabbit.

The greatest competitor to rabbits are chickens and chicken breeding programs have been very successful at producing a relatively large amounts of food in a short period with few inputs. It is possible that, with sufficient demand, a fattier, lower-input rabbit could be developed, but it is unlikely that demand would increase sufficiently without large cultural shifts.
