If you are interested in data also check how many percent car purchases are done because wife wanted them. Cars salesmen in their training are specifically told that a guy showing up without wife isn't serious about the purchase. They will always tell you to come back with wife. Because she is the one telling the guy to pull the trigger. You just pull the trigger. But you won't do it without her approval. The same with house.
And how is it? Complain that you don't make enough money when you already spent 70% of it? On the consumer market. Because in your world where 70% of money is spent on the consumer market has no impact what-so-ever on how the businesses spent their money or how they invest.
Don't pretend to be too dumb, some may believe it.
