Yeah, especially pop-economics and economists that the politicians trot out to promote their latest policies, or the guys trying to forecast the future of some part or another of the economy. And overall economic conditions change a bunch, all the time. Hence the aforementioned hesitance. Unfortunately good consensus surveys only come out every so often and then you have trouble looking them up if you aren't somewhere with JSTOR, so.

But, that said, economists in general have been pretty consistent on a few basic principles. Supply and demand, the impact of price controls thereupon, et cetera. And if you think through enough of that you might begin to think that the EITC is a better vehicle to help out the working poor than a minimum wage (since it doesn't cause unemployment or promote unnecessary investment in automation to further damage employment unnecessarily...) It's been known to happen, anyway.
