Tennis was devised by the British as a leisurely pursuit for the wealthy classes. Most modern-day sports find their origins in the British upper classes of the 19th century. While my forebears were shipped across the world in prison hulks, left to burn in the Antipodean sun, the people who sent them down were holding parasols and enjoying tennis at garden parties on some rich person's back lawn. So yes, tennis' origins are upper class.
If you think badminton is a socialist-inspired opiate of the masses, then the DPRK-made kimchi has obviously rotted your brain.
