>billions go into inflated transfers and club losses that generate little beyond spectacle
"Club losses"? If you pay a football player 100k to play a match, even if the point of the match is nothing but spectacle, that money doesn't evaporate. The player will spend it on the economy. What else could he possibly do with it besides spending it or tossing it in a fire? If a club spends 10M on something entirely frivolous -- say, a giant concrete football -- that money also doesn't simply disappear, it's used to pay the people who will make the raw materials and the people who will design and build the thing. Only individuals and distinct entities lose money. An economy never does.
