Ok, so what do they mean by “bring something to the table”.... By this logic, a pizza delivery guy can offer NOTHING to a girl who comes from a multi-millionaire family.
Maybe he's delivering pizza because he recently returned from a Americorps mission helping to set up irrigation systems in an impoverish region. Perhaps he recently got laid off from his work at NOAA as climate scientist because trump doesn't believe in that and the pizza guy still has bills to pay, so he takes the work he can get. Maybe he's an sculptor that delivers pizza at night because he spends his days in hi studio chipping away at a giant chunk of marble because he can see a beautiful object in that rock and just needs remove everything that doesn't belong.
A person can have more value or character because of what they do outside of how they pay their bills rather than inside of it. A girl from a multi-millionaire family may have a trust fund and doesn't need to earn any more money so she could choose a mate that has made a life of meaning. Hell, if I didn't have to work for money I'd love to so many of those things I listed above.
