Oh, sorry.  I'm not claiming that this what definitely occurs.  I'm saying that this is what needs to be researched on a case by case basis before one can claim that currency devaluations are a bad thing for social equity and welfare.

The same question goes the other way:  What evidence do you have that wealth is transferred from workers to owners when a currency crisis occurs?  It might just as easily be a transfer of wealth from capitalist-owners to capitalist currency traders and thus have only minor welfare effects in terms of workers and other more vulnerable populations.
