Obama's statement was made within the context of economics.
In that same context, if you think that you don't have a "fair chance" now then you are a whiner. Most likely, even if someone else agreed to offer you a portion of their "share" you'd watch the opportunity go by while you continue to bitch .
Economics, social issues, politics and LIFE are not necessarily fair. If you're willing to learn and work hard you will be rewarded with "chances" that will ultimately increase your "share".

This, I believe is the American Dream and yes, it does still exist. There are those involved in politics (and apparently here in Martin Luther King JR County) that do not believe in this principle.
