Our common sense is that the stadium has employees that get payed to do this, with the money we spent on the tickets. If people were to advocate we clean the stadium ourselves, it could be viewed as us denying those employees the opportunity to be useful to the stadium and thus continue having a job.

I'm not trying to say one approach is better than the other, just explaining how I understand the overall western view on this.
