A better question would be why would you leave anything material for your kids? A good eduction and guidance through life should suffice. The rest should be invested in good governance.
Hope for the best, but plan for the worst.
Look, we all know that's not true. It's good to give kids a leg up so they don't suffer unfairly in this unfair world.
Why not give it to literally anyone else? Why not give your money to me when you die? I'm sure your gut said, obviously not, why would I do that? That's how I feel about inherited wealth.
After all, wouldn't receiving that help that they didn't earn just automatically turn them into a bad person?
I guess we should just burn any extra money we have! Can't be letting people having something for free that they didn't earn!
And if I could choose, I would highly prefer paying my taxes not from my income when I am alive, but from the estate I leave after I am dead. For some reason that is completely mindboggling to me, this preference seems to be quite rare...
