Choose your favorite country that isn't Zimbabwe or North Korea, and then find a good or service that people (choose your favorite %-ile) have less of today than they did before free trade.

If you can't find such a good or service, then free trade has helped consumers.

You can only validly make that assertion if you can find somewhere where all else has held equal. Otherwise you'd be making a logical leap without accounting for a bunch of confounding factors.

I also said nothing about whether or not free trade in general is beneficial. What I addressed was the unsupported blanket assumption that free trade will automatically benefit consumers without any kind of qualifications.

As I said: It very well may do, but for that to be true in any specific case, then a number of other factors needs to line up as well.
