In 1800, 80% of the world lived in extreme poverty. Now it's under 10%.
Fact is, the vast majority of the so-called "exploit[ed]masses" rose out of poverty over the same period of time that capitalism established itself as the primary economic system the world over.
So who were they all exploiting, to get out of poverty? Each other?
Except it's done more to solve it since anything that preceded it, so it's not only not funny, it's a misleading/disingenuous talking point.
