Sports can be weird and very fluid indicators. In Australia where I grew up Rugby League was played in public schools and Rugby Union in private ones, so union was associated with wealth. 20 years later union is often played in public schools in the poorest areas by migrants from the pacific islands and the indication is reversing. Every second house a swimming pool there (and beaches), so swimming wasn't seen as a wealthy activity like it is in other parts of the world/country. If you compare between countries it gets even weirder, we inherited almost all sports from England but for them tennis and cricket are they snooty sports, here they're firmly working class. Soccer and basketball for whatever reason seem to hit that egalitarian sweet spot.
