Marx thought the French Revolution demand for equality was fine for its time but outmoded by later, superior analysis (class struggle).
The old demands for equality were equality before the law, not demands for everyone to be literally equal but you'll definitely find a lot of Western leftie on that Harrison Bergeron shit.
There were some 19th century writers who thought wages should be more equal but Marx criticized that. He thought in lower stage socialism workers should be able to take from the common stock the equivalent of what they labor to put in. IOW, if you work longer, or harder, you'll be rewarded.
