Is it a Mitzvah vs a meritorious act to say Kaddish?

Most kids are only too quick to grab the Yerusha (inheritance) from their parent(s). It’s not a Mtizvah to do so, but if you do, then you must give Tzedaka from it (that’s a Mitzvah).

They take Shiva (SEVEN days) and convert it to one minyan or two. That’s not seven days mourning. Don’t worry, they will take seven or six or five figure inheritance without asking the Rabbi much quicker. It’s just “too much” to sit for seven days and mourn the loss of a parent etc

With this in mind, I noticed the Jewish News had an advertisement stating it was a MITZVAH to say Kaddish. I’m not learned, but I don’t know of any Mitzvah to say Kaddish. It’s a well known Minhag to say it at least once a day. I don’t like the idea of taking money for Kaddish when that doesn’t also include trying to educate and carry out the idea that Shiva and Shloshim are Halochos Beruros (clear Mitzvah) and teach these. Earn your money.

Perhaps this is an old-fashioned approach, it needs to be a less opportunistic “chasing coffin” exercise and actually involve doing something about teaching people the Jewish way in Death and Mourning. It’s a Dying Minhag, unfortunately. “Give a few dollars to someone to say Kaddish” and all is good.

Oh yeah, Minhag Yisroel, Din. You can do better than that.
