As an individual sporting star/sensation, the person is likely to affect the economy far more than an electrician or most other jobs. I'm not talking about tax on earnings but more the media coverage which leads to massive view rates during competition, which leads to sponsorship, also leading to infrastructure development for said sports, employment through that, the effects that will have, etc.
I speak from living in Japan, but I imagine it's also easy for you to understand given it'll be similar in China with renowned sporting stars. Maybe more than Japan.
