In heaven, the hierarchy will not be as on Earth, the rich and famous will likely not even be there, and the poor humble Catholic Mestizo may be up in a higher order. In Heaven it is all about the true Faith, Catholicism lived.
For a Catholic, the foremost priority in marriage is finding another Catholic, and by Catholic I mean a person that lives Catholicism. There are scarcely any of these persons in the world today. If that rare person is of another income class, nationality, race, I would snatch her up before someone else does.
For every taste, God invented a color. To each his own. In the world (outside of the true Faith lived), you can't regulate, outlaw, who a person can and can't be attracted to, it is like trying to stop an earthquake by putting duct tape on the crack. You can't fight nature.
