The quote is from the Manifesto of the Communist Party:
No sooner is the exploitation of the labourer by the manufacturer, so far, at an end, that he receives his wages in cash, than he is set upon by the other portions of the bourgeoisie, the landlord, the shopkeeper, the pawnbroker, etc.
I understand what this quote means, but I do not understand the way it is worded. Marx uses "no sooner" with "so far", "at an end", and "that" before he gets to using "than", which seems to be the familiar construct. Can someone help untangle this one for me?
