Barack is supposed to support Beyoncé financially with less than 20 million dollars networth, self dragging isn't the term
Obama can only go so far, that's why Beyonce had to give back those Grammy's that were bought, and that's why Keri Hilson finally has her cake business going since Beyonce is buying them for her collection
Touring, writing, fragrance, producing, clothing lines, endorsements, partnerships with companies is how the big dogs get them dollaz. None of these girls are getting a lot of money from alone unless their label has a deal where they receive most of the profits, they are Writing AND Producing their material.
Even if you're writing and producing your own material alone you have to also have success for those royalties to translate into anything.
None of the pop girls are making money exclusive from songs on the radio, and album sales ONLY.
