WHY do "rappers" rap about shit they DONT have??

for ex: riding in bentleys,throwing money at bitches, so much bling they need help lifting it,poping bottles of crytal, being the KING of hit hop and on and on and on and on and on...

BUTTTTTT they cant even pay for their own STUDIO TIME?

why cant everyone just BE REAL!!!  i have NEVER heard a rapper rapping about EXACTLY WHO they are and EXACTLY what they really do.

for ex: i walk around thinking im the shit

          but when my mom calls me to get my ass home

          in my pants i shit

          i was late bcuz i didnt have a ride

          ya, i DONT have a car THATS RIGHT

          im rolling in my civic sitting on 12's

          my stereo not blasting bcuz i aint got none

          woke up in the morning in a bed of money

          it was monopoly money but hey, its still money

you know....things like that 

just keep it REAL!!!     

let me know your thoughts =)

p.s. i am NOT the red cross here people..thers only so much i can help!
