This is a classic "motte and bailey" argument.
Someone who makes this statement this really want us to equate it with racist chattel slavery - the most heinous form of worker exploitation in modern memory. "Oh, I just meant: {the most common type of work in human history}" as a retreat is not very compelling.
> the most common type of work in human history
Surprised to see someone casually admit that the most common type of human labor is slave labor.
I don’t think that’s true, words just tend to diminish in strength over time towards a muddy middle. Look at how basically anything gets labeled “fascist” these days.
For an older example consider “awesome” (literally: inspiring awe)
