I do wish this is a sarcastic comment, can't tell anymore these days.

Since there is no homepage linked on his profile, I would think it was sarcasm ..

Still, to adress that point:

"isn't it good for society, and thus not such a bad job, that fools are parted from their money"

It is overall bad, as it creates an atmosphere of distrust and distrusting everything costs a lot of energy.

Unfortunately the hustle gurus usually spend it on making the world even worse: more scams, content promoting scammy lifestyle, paying scam buddies, paying off politician to pass scam friendly laws etc.

I don't really care (that much anyway, I do care a bit) that some useful idiot went broke buying into yet another crypto scam. I do care about the guys running the operation getting more resources though as they will use them to make the world I live in worse.

Consumers make the world worse, too. The housing bubble exists because useful idiots are willing to pay beyond reasonable market value, destroying prices for everybody.
