As a life long recipient, all I can say is yes it is true us good looking people get more and get paid better (while also more easily getting hired for jobs etc).
As you can see humility may be a trait that could at times be mistakenly projected onto my lovely beautiful self. ;-) HAHA. I so, however, try to add intelligent, ironic humor as a bonus to make up for this. :)
(Although, of course, ugly people make up for it with more sex.)
