Hip-hop star Kanye West has curbed his spending in light of the economy.

He tweeted this morning, "I know this is not a very rapper thing to say but I haven't bought a new car or piece of jewelry (sic) in about 2 years..."

He later tweeted, "There are so many broken systems from the economy to school systems jail systems... we need experts for this..." and "We need scientist and top world designers to directly affect governments."
