I have a feeling more young white people spend too much time on the negative Internet then blacks and hispanics.
On average white America is pretty spoiled. I'm not sure if I wanted use that word, so don't over think it. Its just that more have been conditioned to expect a certain reality, while other groups understand that that's not the case.
On average most white parents simply think that their children are going to succeed and they don't prepare them for the possibility that that won't happen. This is true regardless of most incomes In the United States wealth has been growing, so most people do not come from a background of great privilege, they come from a background of consistent comfort since the 50's.
