Should Taxpayers ever fund large stadia/arenas?

[beaver2.0]

I'm not going to say never but I'm generally against it for Big Four teams that get massive amounts of funding and then tax breaks.  It's absurd to get public funding for a massive stadium surrounded by acres of parking lots that will be used a dozen times a year.  Arenas/urban stadiums are a different story and I don't mind cities helping out as long as they aren't providing a significant amount of funding and the venue can be used by other groups so it doesn't sit there empty for most of a year.

I don't fully trust the argument that building new stadiums is an economic benefit.  From experience, the the DC region's largest stadium, Fedex field, doesn't exactly strike me as a place that has benefitted significantly from stadium construction.
