The consumerism is from the D-Boy era in the 80s. Being fly has always been a part of Hip Hop culture, it just didn't take on the importance that it takes on now. Also, once again I think we received two different messages from the gangsta rap era. To me, I felt like these were the memoirs of survivors of the crack era and even some of its participants. The people that control the culture will portray it as they want in order to get a desired effect from the culture's consumers. Take Pac for example, he's always portrayed merely as a thug, his image is distorted to the point he's deified, vilified, and oversimplified for people who don't know of him. The actual message he was sending was never emphasized because it was positive and a remedy. In fact, you find positive messages in quite a few gangsta rap records. Just because your not playing it safe and giving a raw depiction of what's really going on doesn't make it ignorant(if done correctly of course).
Being fly done went from "My Adidas" to the unrealistic Puff/ Cash Money shyt where there were Bentleys and million dollar houses that took over the late 90s and fukked it up for the regular man, IMO.
People downplay his black power message pre-Death Row era. The balance of positivity and negativity been unbalanced to the point where positive messages are few and far in between. If it was done correctly, we would have seen more Q-Tips "Renaissance" albums and more Nas "Untitiled" concept albums that described the history of black oppression. Hell, these hardcore artists can't even hold to Ice Cube's first few albums.
