That's not the way it goes, though. For generations, royals (and other wealthy folks) have married their children away as pawns. These aren't/weren't seen as a chance to redeem poor choices, but as a way to keep wealth to a small circle. People have been seen as monetary items for centuries. If we want folks to not be used in such ways, we actually have to legislate it. Make sure children have rights and freedoms and that they know about it. Have inheritance laws that make sure each child gets some money from a well-to-do parent, even if they marry someone poor. Make sure farmers worldwide are well-equipped. Educate folks, treat them as equals (which doesn't happen now).
