Furthermore, the author ever addresses other forms of leisure where people are paid to participate, such as sports. Does the NBA devalue the pickup game played solely for bragging rights? The other problem I have with this argument is the fallacy that leisure activities were not class based in the past. Polo would seem to be a fairly obvious example, very few people can afford the horses required.
