I dunno, while they didn’t tell me to ask for cash, my parents basically made me invest any cash I got as gifts, plus everything I earned at summer jobs. I think that this kind of “investing by default” mindset (plus getting my own desktop computer for Christmas at age 11) extremely significantly impacted my current life in a positive way.
Also, learning to use Excel by playing fantasy stocks during the dot-com bubble, and having a Lycos homepage “Portfolio” widget just like my mom did is a fond memory for me, and zero people on Earth would call me a finance bro today.
The major difference is that in all your examples you were already getting cash. In the article, the poster is incentivising their kids to get cash instead of something else specific. From the article:
> we suggested that instead of asking for physical gifts, he ask for their equivalent in money.
For their equivalent. In other words, the kid has to decide something they want then deliberately choose to not get it so they can “invest” it and see line go up.
It would’ve been different if this had instead been a case of “grandma just gave you an envelope with cash; if you don’t have plans for it, how about investing?”. Which works on many levels, they could’ve also spent some portion of the money on something they wanted then invested the surplus, or a myriad other options.
