There's no need to be rude. Everyone has different experiences. Not everyone is assertive or has the opportunity to learn to be assertive. Especially when social expectation is against them.
You're missing the point of what assertiveness is. It's about creating opportunity, not sitting on your ass and waiting for the world to cater to your needs. Life is what you make it and one has nobody to blame but themselves for where they go. True, we don't choose the starting point, but we do choose the destination.
