Jay-Z will raise money for underpreiv kids by staging benefits concert or something. Sorry by I don't fill like reading and parphrasing so I'm just going to copy and paste this article:

"This year, Jay-Z is making sure that Santa brings more diamonds rather than lumps of coal come Christmas by holding a special Thanksgiving benefit concert on Thursday at New York's Hammerstein Ballroom. In previous years, Jigga and crew have handed out donations in their old neighborhood of Fort Greene, Brooklyn, but this year, Jay and his partner, Dame Dash, have partnered with the New York City Mission Society to raise funds for underprivileged city kids with a sold-out concert featuring performances by Jay, Beanie Sigel, Freeway and other Roc-A-Fella artists. Monies raised will also go toward the rapper's new Jay-Z Scholarship Fund."
