One of the main issues is the fact that you nikkas think "HIP HOP" is limited to rap music. The majority of people that I know that listen to rap don't really participate, not only in rap, writing/producing, promoting ect. but they completely ignore the other elements, there is an imbalance between the mouth and the rest of the body of Hip Hop in total.
The difference between 1st gen on down is that people increasingly became more passive in their experience with the culture. You have people thinking they can sit back with an ipod and "listen" to hip hop when it's truly something you live. At it's root you couldn't sit up in your apartment and watch nikkas break dance talmbout you're hip hop, you at least had to come down and mingle with the crowd to not only see but FEEL what was being expressed.
People don't live it anymore...they sit back waiting to be entertained, and when they aren't entertained by what they allow people to give them, rather than look elsewhere, or change their approach to how they experience the culture they point the fingers at the entertainers instead of seeing shyt for what it is really is. You're bored because you're boring...hip hop is predictable because you're predictable.
