Bread and circuses, eh? I don't see anything inherently wrong with that. I could say more but Cata has basically already said everything I was gonna in the post above.
As far as taxes on watching live TV goes, that is no longer being done on behalf of our public broadcasters, with the tradeoff that they also broadcast commercials, has been that way for decades now. Of course we're Dutch and I don't expect that model to be widely adopted. They also broadcast a wide variety of foreign and domestic entertainment programmes, but again I don't have any real objections to that, in large part because of this:
Particularly when it comes to culture and entertainment, our government also subsidizes, theater, opera and numerous festivals, in addition to musea. Yet unlike our public broadcaster they are often still not very affordable in part because theater and opera owners still get to "cultivate an ambiance of exclusivity", that basically meant no people like me when I was growing up can afford that or are even allowed in ever. So those taxes go to funding entertainment for the well-off sections of the population exclusively.
Of course much like you and Cata I don't like a lot of things my taxes help pay for either, chief among them giving huge tax breaks to super-profitable megacorps and no strings attached bailouts to big finance. Particularly the no strings attached part.
