Apart from the lack of personal fulfillment, isn't it good for society, and thus not such a bad job, that fools are parted from their money? After all, consumers decide what our society does. If a consumer is not able to recognize a scam, how can society trust them to make meaningful decisions? A hustle guru will spend their money on fast cars and thus at least support state of the art engineering.
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.
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.
I was once pitched a gig that, after you boiled away the flowery tech contraptions, amounted simply to “run your own scummy leadgen business.” I felt like I had to take a shower after hearing that pitch. Wouldn’t it be nice if I didn’t have that part of my brain that recoils in disgust at treating other human beings as “leads” to be bought and sold?
