Unironically UBI or something similar could eliminate the need for -most- people to resort to petty scams.
It may make pity scams less effective though so I'd expect the implementation to change to focus more on creating urgency and less on altruism.
The prospect of not being able to pay for food or rent carries a desperation that isn't there when just wanting to buy a video game or hire a Hooker :)
Maybe with hard drug addiction, but that's a different societal problem to tackle.
> it just re-baselines
If fewer people are chronically -desperate- for money, it could leave a smaller workforce pool available to professional scammers for "hiring ghost writers to pump out low quality ebooks" or "paying people to leave 5 star reviews" etc
