> No-one ever says "We spend billions on Football; let's spend it on poor people instead", or "We spend billions on the music and film industries, let's shut those down and instead tax everyone for the average entertainment spend and send the proceeds to developing nations". Or defense for that matter.

People say both quite a lot. Well, in case of the more general "industry" it's more like "let's roll back the spending quite a lot, except defense, shut that one down".
