young men pay more for car insurance than young women (today). This is based on statistical models. Should they be outlawed?
EU has outlawed them. their argument is that differentiation is only valid if the difference is the actual cause and not merely statistical correlation.
Ironically, in the US it is ok to charge men more for car insurance, since they cost more in aggregate. It is illegal to charge women more for health insurance even though they cost more in aggregate.
