Not sure if I understand your question but I assume the point Chris is getting at is that the copies are mass produced, affordable pieces of furniture for the masses. Herman Miller 'originals' are now priced beyond insanity and reserved for, quite frankly, the wealthy.
The idea behind the pieces in the first place was to create good, affordable furniture that most people could afford. A democratisation of design if you like.
Now though, when they’ve been trendy for ages the producers have increased prices beyond what even well off people can afford.
You could argue that the reproduction eames are more in keeping with the original ethos.
Not that I would, but still…
