Free Trade (Off topic alittle)

It seems like econ people love free trade. All the questions in schweser seem to be pro free trade. Is there anything in economics against free trade?

not that i remember… but some arguments against free trade are total BS, some have a little bit of a point… probably good to know which ones are total cr@p and which are reasonable but still wrong like, “inventory dumping” is total BS, but i think “national defense should be domestic” has some legitimacy although still not a good reason to not have free trade

CFA says unemployment, infant industries, dumping, jobs, culture, and a few others. But all in all, the CFA curriculum says that all these arguments are not valid.
