an artists lie

What i took away from last class was the relization of our suposid "ever changing" society. Sure we are always changing in teh ways of technology, but our changes are more of an adaptation of what we have had in the past. Take our clothes for example. teh clothes from teh early, mid, to late 1900s we saw change. Conservaite, to 50's house wife, to teh 60's and hippies, to teh 80's and huge hair. but as we have progressed ot teh society we have today i see the "changes" we have as more of adaptations or incorperations of what we once had. I see what i wore today and nnotice that i wore bell bottoms. these pants were pants of teh 60's/ 70's and have been brought back.
I looked at teh post modern work we looked at last class and saw all teh works or duchaump and andy warhol. all of thir work was of the ready made. Granted they did make their work their own, but they adapted what was there or what once was to make it seem new when i reality what they created was not really created at all. They made money off and idea or theory which is simply rediculous. It is as if they are selling us our own shit back to us. The only people who can aford their art is the people who control the companies who created it to begin with. I cna apreciate the idea behind teh art, but why invest in something you can creat yourself or create on photo shop?
