Well done, Reinhard and Gerry.

Some spelling errors in Reinhard's lyrics will be easily corrected by anyone who wants to research further. Here I found this or a similar song mentioned as "created by Yiddish lyricists and musicians in the early 20th century" and apparently suggesting its origin to be in the USA. Inhuman working conditions are not a monopoly of Tsarist Russia.

Gerry, the song you are quoting is obviously the very same that my source mentions, just different verses. Here is a rendering that seems quite authentic to me. Here a lady talks about the song in English, including some translation. Note that the song is about a woman named Yachne Dvoshe, whom my source erroneously confuses with Bloshteyn's fictional character. Pirozhnikov (Пирожников) is a well-known dynasty of Jewish musicians in Vilna (Vilnius) and Russia.
