When people say things akin to "If white people had to live in poverty like race x does" miss the point entirely. The fact some cultures have achieved greater prosperity than others is - in fact - proof of that cultures propensity for "greatness". The simple fact that most whites don't live in abject poverty (and ignorence) could explain why switching roles would only be temporary. the race/culture that is superior will rise to the top much like the proverbial "cream" that they represent. Much like Mike Tyson trading places with Bill Gates, it would make little difference in the long run whom started out where, the eventual outcome would be MicroSoft would be ruined, and a new software company would rise elsewhere. Most people (who are truthful to themselves) know this, the rest can continue to 'Cast pearls at swine'
