people will always try to use the argument against that tho. Laos will say 'well u americans had slaves too' and that'd be true, but the americans got rid of slavery 150 years ago along with the rest of the world around that time, and Laos is still hanging on. its just like when people find out china is putting anti freeze in its touthpastes, and some people say 'well we used to have arsenic in things. well yeah, but that was before anybody knew it was dangerous, and yet everybody knows antifreeze is dangerous, and china still uses it.
