Well off vs poor origin champs

[goldenera]

I was thinking how tennis rewards talent and hard work no matter if you come from a well off or poor social status
Wouldm t.be great an all time match between great champs coming from well off families vs those from poorer origins?
Here is my pick
USA
Well off..Tilden,Mc Enroe,Sampras,Tanner,Vitas
Poor..Connors,Gonzales,Budge,Courier,Riggs

Australia
Many many champs socially divided
Well off..Rosewall,Cooper,Stolle,Newcombe,Dent,Fraser,Quist
Poor..Laver,Emmo,Roche,Brommwich,Aexander,Hoad,Anderson
Many mixed great doubs like Alexander-Dent,Emmo-Stolle,Hoad-Rosewall,Bromwich-Quist and Neek-Roche
Rest of the world
Well off..Vilas,Pecci,Sanchez,Borg,Becker,Drysdale,Mottram
Poor..Santana,Perry,Orantes,Edberg,Panatta,Gimeno,Okker,
Of course we cannot define those from communist countries like Nastase,Lendl,Kodes
Borg and Agassi would be in between,midest middle class

Any more signifiant cases?
