I seem to recall that the article on labor productivity and local winning teams was in the Post, but it was at least a few years ago. If you'd like some anecdotal evidence, talk to some Redskins fans on Monday mornings after a loss, which is pretty much every Monday morning these days. The Post editorial this a.m. goes after the China trip you reference. There seems to be no evidence from the city that prior trips have led to greater investment, created jobs, etc.There is some populist grandstanding among anti-stadium politicans. It depends on how the argument is being crafted.Finally, in an ideal world, I agree that owners should build their own stadia. But that's just not how these things work anymore. Nonetheless, the stadium is not a "give-away;" it would be owned by the city, which would collect rent and taxes on its use.
