But you are the exception. The problem is not really weak passwords, it's re-used passwords. A lot of people just use one password and they use it everywhere, so as soon as it gets cracked once, their accounts can be compromised all over the place.

The best thing I ever did for my parents was teach them to use different passwords everywhere. Against conventional wisdom, I get them to write them down in a book, because for them, keeping a book secure is much easier than knowing what to do to keep their computers secure. We already know how to keep physical objects reasonably secure, we do it every day with our credit cards, passports, jewelry etc.
