Thank you, I did not know about tzedakah, and am glad I do now.

I tend to agree with you about phrasing (note that I use the term "responsibility" in the title), though I do shy away from the idea of enforcing such responsibility. I would rather it be voluntary but seen as a normal and expected act, not a gesture of some exceptional virtue. Fear of looking like I was trying to portray my actions as the latter is one of the main reasons I never said anything about this until now.
