What an incredibly bad idea!
How do you underwrite the sale of female equity? My wife has taken about 3 years off to raise our kids. This would have a negative impact on a bankers ownership of her.
If this is the future, let's skip the bankers and form trade guilds. I'd rather payoff somebody to get my kid into the IT Guild than sell a piece of him to some banker. This is the kind of excess that sparks revolutions.
