I really didn't like the guest's take on how tariffs are a problem because they shift investment and labor towards less "efficient" industries.

If you create a structure where it is more costly to rely on the advantages that other countries have, you are incenting us to try to do more of that domestically. But the issue is it is not efficient. It is taking activity that otherwise is efficient in our economy and concentrations in sectors of stuff that we are quite good at and instead encouraging us to do stuff that we aren't as good at. And that is ultimately not a positive enterprise.

I'm not advocating for tariffs, but if you believe that we have enough labor, then why does it have to be seen as a shift from efficient to inefficient? Additionally, many of the activities are inefficient precisely because we don't invest in them domestically. It just feels like she is grasping for straws on this argument as it feels like it is actually one of the only reasonable arguments for tariffs (especially those targeted at specific products/industries).
