"I dont think they are genetic at all, "

We clearly disagree on this point. And to support your arguement, you'd tell me that testosterone doesn't make a human, regardless of gender, more agressive?
I would grant you that aggression can be socialized. But the real, hard core, I want to beat your brains in at all costs aggression is generally associated with testosterone. Think I'm wrong? Try some. Or, perhaps you have?

It doesnt matter how much testosterone you have, if you dont have a college, law school, or medical degree - you still wont make as much money. Uneducated males with lots of testosterone will still be able to get jobs digging ditches to work off all that testosterone, but their paychecks will be lots smaller than women with advanced degrees and who are in management.
