Well here's the irony in that:
Those chairs came out of the industrial movement around the first and second world war. That was a time when everybody was fighting, and if you lived in Europe (especially around dockyards and factories) there was a good chance that your home was destroyed. People were fed up with the bourgeois ruling class who's style was very ornate with lion's feet on every chair leg, tons of photorealistic paintings around the house, and just more shit than they would ever need. (At the time unpopular) painters began to deconstruct the bourgeois lifestyle with paintings that no longer were very realistic, technical, or hard to replicate. You have russian deconstructivism, De Stijl, all slowly taking away the ornate and replacing it with the bare essentials.
And what else was happening at that time? War gave way to a huge uprise in factories, manufacturing processes, and affordable products. Many architects and interior designers took it upon themselves to help their countrymen rebuild after the war by creating cheap houses and furniture that could be manufactured on an assembly line, thereby making them quickly built, and affordable to the working class who would be coming home to nothing. (This is where condos, duplexes and the projects came from, because you needed a way to build nice livable homes close to where these people worked--factories and dockyards--at the rate of 2 houses a day)
So all the chairs that have been posted are meant to be affordable to anyone, but when they became popular with the bourgeois crowd, they went from being ikea to art society, and prices went from $20 a chair to $2000.
You can still find affordable replicas out there. You just have to look.
