Around the world, family-arranged alliances have gradually given way to love matches, and a transition from an agricultural to a market economy plays a big role in that transition
Parents historically controlled access to inheritance of agricultural land. But with the spread of a market economy, “it’s less important for people to have permission of their parents to wait to give them an inheritance or to work on their parents’ land, So it’s more possible for young people to say, ‘heck, I’m going to marry who I want.'”
Modern markets also allow women to play a greater economic role, which lead to their greater independence. And the expansion of democracy, with its emphasis on liberty and individual choice, may also have stacked the deck for love matches.
