I was wondering how should I interpret this verse from the old union song Solidarity Forever:
What's the ought with have in common with those greedy parasites?
I'm split between
What responsibility do we have towards those greedy parasites?
What responsibilities do we share with those greedy parasites?
The first reading is more consistent with the theme of the song but without contex the second seems more correct (a common ought -> a shared responsibility), which makes me think it might be an idiom or an old usage I'm not familiar with.
