Would the international corporations exporting labor really be in a deficit if they came back to the west?

So I've been wondering, considering the profits that, for example, the profits that the clothing or shoe industry make, which from my understanding are quite Massive, considering the low cost of not only vietnamese labor, but the cost of production in general, how much would these corporations lose profit if they came back to Europe ?
Would it be to the point of being in a deficit?

I know there would be a problem for the machines needed for the industry, probably a cost for a change in the supply change, as well as a cost of labor efficiency considering that the European workforce is probably less skilled than their Vietnamese or Chinese counterparts.
Are all of these so costly to make it so that these industries would just be in a straight deficit? And if we were to disregard these problems, would the industry still lose money for other reasons, so much so that it would cause deficit?

I've been wondering about this topic since talks of reindustrialisation have been present for a few years.
