It's my observation and opinion. Michelle, Princeton/Harvard (Juris Doctor) from a working class family - black, BTW - in elegant gowns, married a peer from a law firm. 
Melania, doesn't have the degree she once claimed to have (oops), "modeled" for nude photos, married a very rich, much older man.
Barack also made his own way - he didn't have millions of dollars in support from Daddy.
The difference is night and day - black and white (pardon the pun)
Donald reminds me of Roseanne Barr - in her own words - "whites trash with money" - except that she earned all of hers.
