When I find myself agreeing with the teamsters, it is a very unusual situation, indeed. My reasons are motivated more by public safety concerns than monopoly control of shipping.
It's not that unusual, really. Protectionists aren't that far distant (philosophically) from leftists. Take this thread, for example. There are a number of responses that could've been lifted from Ralph Nader's group, Public Citizen.
And the appeals to emotion? Look at my photos! LOL
