That's one kind of encouragement, sure, but not the only one. I'm not even arguing money is necessarily the best reason. All I need to show is a refutation of the notion that there is some kind of biological/inherent impediment for women to be successful at tech.

PS: for that matter, my personal experience -- coming from a family of scientists who aren't rich, and which includes my mom -- is that there are other factors at play beyond money. Note I don't live in the US.
