Fishing is a hobby carried out by very posh people indeed.

Dog fighting and cock-fighting have traditionally been done by poor people. That hasn't kept it legal.

Hare-coursing is pretty working-class too, and that's been banned.

All in all, seeing this as particularly about class doesn't really add up.
